plant tissue
Plant organs such as roots, stems, and leaves are composed of tissues which are groups of cells that perform specialized functions. The three main tissue types are dermal tissue (epidermis), ground tissue (parenchyma, collenchyma, sclerenchyma), and vascular tissue (xylem and phloem). The epidermis forms the outer protective layer, ground tissues fill the interior and provide support, and vascular tissues transport water, minerals, and organic compounds throughout the plant. Each tissue contains further specialized cell types that contribute to the plant's growth, protection, nutrient transport, and other processes.

Plant tissues
This document discusses plant tissues. There are two main types of plant tissues: meristematic and permanent tissues. Meristematic tissues are undifferentiated and can divide, while permanent tissues have differentiated and lost the ability to divide. The three main permanent tissues are dermal/protective, fundamental/supportive, and vascular/conductive tissues. Dermal tissue covers the plant, fundamental tissue provides structure and storage, and vascular tissue transports water and nutrients. Within these tissues are cell types specialized for different functions like photosynthesis, support, and long-distance transport.
Tissues
There are four main types of tissues in plants and animals:
1. Meristematic tissue, found at growing tips of stems and roots, is composed of actively dividing cells responsible for growth.
2. Permanent tissues have differentiated cells that perform specific functions and do not divide. These include simple tissues like parenchyma and complex tissues like xylem and phloem.
3. The four main animal tissues are epithelial, connective, muscle and nervous tissue. Epithelial tissue lines surfaces, connective tissue connects and supports, muscular tissue enables movement, and nervous tissue conducts electrical signals.
Tissues
There are four main types of tissues in both plants and animals: meristematic tissue, permanent tissue, epithelial tissue, and connective tissue.

Tissues
Tissues are groups of cells that work together to perform a specific function. There are four main types of tissues in animals: connective, muscle, nervous, and epithelial tissues. Connective tissues provide structure and binding, blood and bone are examples. Muscle tissues allow movement and include three types. Nervous tissues make up the central and peripheral nervous systems. Epithelial tissues cover surfaces of organs. Plants also have two main tissue types - meristematic and permanent tissues. Meristematic tissues are actively dividing and allow growth, while permanent tissues take on specific roles and functions.
Plant Tissues for Grade 10 Life Sciences
The document discusses plant tissues and their structure and function. It defines meristematic tissue as actively dividing cells that have not differentiated. Meristematic tissue includes the apical and lateral meristems. Permanent tissues have differentiated, such as epidermis, ground tissues (parenchyma, collenchyma, sclerenchyma) and vascular tissues (xylem and phloem). Xylem transports water and minerals upwards and provides structure. Phloem transports nutrients throughout the plant via sieve tubes and companion cells.

This document discusses the organization of plant tissues and growth. It describes the different types of plant tissues - meristematic and permanent tissues. Permanent tissues include epidermal tissue, ground tissue and vascular tissue. Epidermal tissue forms the outer layer of stems, leaves and roots. Ground tissue includes parenchyma, collenchyma and sclerenchyma cells which provide support. Vascular tissue comprises xylem and phloem. Xylem transports water and minerals upwards from the roots through hollow vessels. Phloem transports sugars made by photosynthesis to all parts of the plant through sieve tubes.
Plant tissues
A plant tissue is a cell or a group of cells that give rise to large number of cell, which is collectively called tissues.

Biology 26.1
This document defines key terms related to the animal kingdom, including invertebrates, vertebrates, feedback inhibition, blastula, protostomes, deuterostomes, radial symmetry, bilateral symmetry, and more. It describes animals as multicellular, eukaryotic heterotrophs and outlines their essential functions of feeding, respiration, circulation, excretion, response, movement, and reproduction. Complex animals are noted to have high cell specialization, internal organization, bilateral symmetry, a head with sense organs, and a body cavity.
Biology 26.2
Sponges contain specialized cells like choanocytes that use flagella to move water through the sponge for feeding, respiration, circulation, and excretion. They have structures like spicules made of calcium carbonate or silica that form their skeleton, and archaeocytes that produce these spicules. Sponges reproduce through internal fertilization and larval stages, and some can form protective gemmules during unfavorable conditions.
Biology 22.5
Angiosperms are flowering plants that reproduce sexually through flowers. Flowers contain ovaries that surround and protect seeds. Angiosperms are divided into monocots and dicots based on whether their seeds have one cotyledon (monocot) or two cotyledons (dicot). Flowering plants can also be annuals, biennials, or perennials depending on whether their life cycle is one, two, or more than two years.
Earth science 13.1
The document discusses Precambrian time from 4.56 billion years ago until the Cambrian period over 4 billion years later. It describes shields as flat expanses of ancient metamorphic rock within continental interiors. Stromatolites are layered mounds formed from algae trapping sediment and calcium carbonate. Earth's original atmosphere lacked oxygen but primitive organisms evolved photosynthesis which began releasing oxygen into the atmosphere around 2.5 billion years ago.
Earth science 13.4
The Cenozoic Era saw the rise of mammals as the dominant land animal, replacing reptiles. Flowering plants known as angiosperms also became the dominant land plant over gymnosperms. Major geological events like mountain building, volcanism, and earthquakes occurred in western regions due to plate tectonics during this era. Mammals were better adapted than reptiles for more active lifestyles through bearing live young and maintaining steady body temperatures.
Earth science 13.2
The Paleozoic Era saw an explosion of life, as the continents of Gondwana and Laurasia formed most of the southern and northern portions of the supercontinent Pangea. During the Cambrian, Ordovician, and Silurian periods, life was restricted to the seas surrounding Gondwana, which contained the continents of present-day South America, Africa, Australia, Antarctica, and parts of Asia. By the end of the Paleozoic Era, around 400 million years ago, all continents had fused into the single landmass of Pangea, and plants first began moving from waterside habitats onto land.
Earth science 13.3
The Mesozoic era was the Age of Reptiles, where reptiles like dinosaurs quickly became the dominant land animals due to developing shelled eggs. Gymnosperms also dominated as the prominent plant during this time. A major geological event was the breakup of the supercontinent Pangea. Many reptile groups went extinct at the end of the Mesozoic era.
Earth science 9.1
Continental drift is the hypothesis that the continents were once joined together and have since drifted apart. Originally proposed by Wegener, it suggests the continents were part of a supercontinent called Pangaea approximately 200 million years ago that has since broken apart, moving the landmasses into their current positions. Fossil and rock evidence support this idea, including matching fossil organisms and mountain ranges found on separate continents today that indicate the continents were once joined.
Earth science 8.2
This document discusses seismograms and the different types of seismic waves that are recorded, including P waves, S waves, and surface waves. It explains that seismograms amplify and electronically record ground motion from earthquakes, allowing scientists to determine the epicenter location using travel time graphs from multiple seismographs. The document also covers historical intensity and magnitude scales used to describe earthquake size and introduces moment magnitude as the most widely used scale today because it estimates the energy released.
Biology 28 2 groups of arthropods
This document defines and describes key anatomical terms used to classify groups of arthropods. It discusses the cephalothorax, thorax, and abdomen found in crustaceans, as well as specific structures like the carapace, mandibles, chelipeds, swimmerets, chelicerae, pedipalps, and spinnerets. It concludes with three key concepts: arthropods are classified by body segments and appendages, especially mouthparts; crustaceans typically have two antennae, two or three body sections, and mandibles; and chelicerates have chelicerae mouthparts and two body sections, with nearly all having four pairs of walking legs.
Biology 2.4
Chemical reactions involve reactants being converted into products through breaking and forming chemical bonds, requiring a minimum amount of energy called the activation energy. Catalysts like enzymes speed up reactions by lowering this activation energy, with enzymes being protein catalysts that facilitate substrate reactions within cells.
Earth science 12.3
This document discusses radiometric dating and how it is used to determine the absolute ages of rocks and minerals. It explains key concepts such as radioactivity, half-life, and how comparing ratios of radioactive isotopes like carbon-14 and carbon-12 can be used to calculate radiocarbon dates for samples. Radiometric dating relies on the fact that radioactive isotopes decay at a constant rate and comparing the amounts of parent and daughter isotopes allows the age of a sample to be estimated.

Fossil and rock evidence support this idea, including matching fossil organisms and mountain ranges found on separate continents today that indicate the continents were once joined.
Earth science 7.3
Wind shapes landscapes through processes like deflation, desert pavement formation, and loess and dune deposition. Deflation is the lifting and removal of loose material by wind. Desert pavement is a layer of coarse pebbles created when wind removes finer material. Loess deposits are windblown silt deposits that form blanket-like layers, while dunes are ridges of wind-deposited sand that can vary in shape depending on wind and vegetation factors.
Earth science 7.2
Much of the weathered debris in deserts comes from mechanical weathering like alluvial fans formed where stream slopes abruptly decrease. While chemical weathering is less common, over long periods clays and thin soils can form. Desert streams are ephemeral, only flowing after rain, and often drying up before reaching oceans due to evaporation and soil infiltration. Most desert erosion comes from running water, though wind also erodes deserts, water does the most erosional work.
Earth science 7.1
Glaciers are large masses of ice that originate on land from compacted snow and move due to gravity. During an ice age, large ice sheets form on continents and flow outward, carving U-shaped valleys and depositing unsorted sediment called till. Valley glaciers are smaller glaciers confined to mountain valleys that flow due to plastic deformation and basal sliding between the ice and bedrock.
Earth science 6.3
Groundwater exists below the surface in the saturated zone where all spaces between rock and sediment are filled with water. The water table marks the top of this zone, and groundwater moves slowly through porous and permeable materials. Springs form where the water table intersects the surface, and overuse or contamination can threaten groundwater supplies in some areas. Karst regions have irregular terrain with sinkholes caused by erosion of soluble rock by groundwater in caverns below the water table.
Earth science 6.2
This document defines key terms related to streams and their processes, including bed load, capacity, alluvium, delta, natural levee, floodplain, flood, drainage basin, divide. It also describes concepts such as how streams erode and deposit sediment according to flow velocities, and how flooding occurs and can be mitigated. The overall work of streams is to shape the landscape through erosion, transportation, and deposition of sediment within drainage basins.
Earth science 6.1
The document discusses key concepts about running water and the water cycle. It defines terms like infiltration, transpiration, gradient, stream channel, discharge, tributary, base level, and meander. It explains that water constantly circulates among the oceans, atmosphere, geosphere, and biosphere in the water cycle. Balance in the cycle means annual precipitation equals evaporation globally. A stream's ability to erode and transport materials depends on its velocity, while gradient decreases and discharge increases from headwaters to the mouth.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
