Animal and Plant Cells
The document discusses the key parts of plant and animal cells. It explains that cells are the basic unit of all living things and outlines some of the main cellular structures including the cell membrane, cell wall, chloroplasts, chromosomes, cytoplasm, mitochondria, nuclear membrane, nucleus, and vacuoles. The main differences between plant and animal cells are that plant cells contain chloroplasts and a cell wall, which animal cells do not have.
Characteristics of Living Organisms
All living things must have five key characteristics: 1) cells, 2) use energy, 3) homeostasis, 4) growth through cell division, and 5) reproduction. The document discusses these characteristics and provides examples of each one. Living things are made of cells, require food/energy, regulate internal conditions, grow by cell division, and reproduce offspring that are similar to the parents. Nonliving things do not possess all of these characteristics.
Plant reproduction
Plant reproduction involves the transfer of pollen from the anther to the stigma, known as pollination. This can occur through wind or animal vectors. Fertilization happens when the pollen tube delivers sperm to fertilize the ovule. The ovary then develops into a fruit containing seeds. Seeds are dispersed by various mechanisms like wind, water, or animals to colonize new areas away from the parent plant. Germination starts when the seed takes in water, activating enzymes to break down food stores that fuel embryo growth into a new plant.
The organization of living things
Multicellular organisms have several advantages over unicellular organisms including larger size allowing them to avoid more predators, longer lifespans not limited by single cells, and specialization where each cell type performs a specific job making the organism more efficient. The structure of organisms is organized into hierarchical levels from cells to tissues to organs to organ systems with each level working together to carry out life processes. Structure and function are also related in organisms, where the arrangement of parts enables them to perform their necessary jobs.
Plant & animal cells
This document provides information about plant and animal cells. It defines cells and discusses their main purpose of organizing living things. It describes the parts of typical plant and animal cells and compares their structures. Plant cells have cell walls and chloroplasts, while animal cells lack these and can have flagella. The document also discusses how different types of animal cells, such as muscle, blood, skin, and nerve cells, are specialized to perform different functions in the body.
Specialised Cells
This document discusses specialized cells and their functions. It provides examples of specialized plant cells like those with thick cell walls that allow bending as they fill with water and have large surface areas for absorbing water and minerals. Specialized animal cells discussed include cilia for moving mucus, elongated muscle cells for contraction, flat disc-shaped red blood cells for oxygen transport, and nerve cells with long axons and dendrites for transmitting electrical signals. Students are asked to order complexity from cell to organism and describe cellular adaptations and functions.

Cell : Structure and Function Part 01
Cells are the basic structural and functional units of all living organisms. There are two main types of cells - prokaryotic cells, which lack a nucleus, and eukaryotic cells, which have a nucleus surrounded by a nuclear envelope. The plasma membrane surrounds the cell and acts as a selectively permeable barrier that regulates what enters and exits the cell. Transport across the membrane can occur through passive diffusion, facilitated diffusion, or active transport processes that require energy. Vesicle transport is also used to move materials within and between cells.

It describes the cytoplasm and cytosol as well as various membrane-bound organelles including mitochondria, ribosomes, the endoplasmic reticulum, cilia and flagella, the nucleus, the Golgi apparatus, lysosomes, and the cytoskeleton. It also mentions cell walls, vacuoles, chloroplasts, and their respective functions in cellular structure and processes.
Kingdom plantae
The document provides information on the kingdom Plantae, specifically focusing on algae and bryophytes.
[1] It describes the characteristics of algae, including their sizes, shapes, pigments, food storage, and modes of reproduction. [2] Bryophytes are described as the first land plants and having a thalloid plant body without roots or leaves. They reproduce sexually through gametophytes and sporophytes. [3] Pteridophytes are vascular plants that exhibit alternation of generations between free-living gametophytes and sporophytes.
Specialized Cells, Biology
Specialized cells in plants and animals have unique structures and functions. The document discusses several types of specialized cells including red blood cells, white blood cells, nerve cells, muscle cells, sperm cells, egg cells, root hair cells, palisade cells, and xylem cells. Red blood cells carry oxygen throughout the body while white blood cells protect the body by killing bacteria. Nerve cells carry electrical signals and coordinate functions. Muscle cells allow movement by contracting. Sperm and egg cells are reproductive cells that combine during fertilization. Root hair cells absorb water and minerals in plant roots. Palisade cells contain chloroplasts to perform photosynthesis. Xylem cells transport water and provide structure in plant stems.
Classification of plants
The document classifies plants into two main categories: flowering plants and non-flowering plants. Non-flowering plants include mosses and ferns. Mosses do not have true roots or vascular tissues, reproduce via spores, and prefer damp environments. Ferns have roots, leaves, underground stems and vascular tissues, reproduce via spore-producing organs on their leaves, and prefer damp shady places. Flowering plants are further divided into gymnosperms like pine trees, which have needle-shaped leaves and bear naked seeds in cones, and angiosperms which have true flowers and fruits containing seeds. Angiosperms include monocots and dicots, distinguished by whether they have one or two seed leaves and

The cell has three basic parts - the nucleus, plasma membrane, and cytoplasm. The nucleus controls the cell's activities and contains hereditary materials. The plasma membrane encloses the cell and regulates what enters and exits. Plant cells also have a cell wall that provides structure and protection. Within the cytoplasm are organelles that carry out specialized functions like mitochondria that generate energy and chloroplasts that perform photosynthesis in plant cells. Key differences between plant and animal cells include the presence of a cell wall and chloroplasts in plant cells.

The basic structure and function of cells
Cells are the basic building blocks of living organisms. They are too small to see with the naked eye and need to be viewed with a microscope. The main purpose of cells is to organize the different parts of an organism and hold the biological equipment necessary to sustain life. There are many types of cells that can differ in shape and size, including animal and plant cells. Animal cells are eukaryotic with internal structures like a nucleus, mitochondria, and vacuoles, while plant cells have additional cell walls and chloroplasts.

The document defines key terms related to cells and describes the basic structure and functions of cells. It states that a cell is the smallest and most basic unit of life, and is composed of a cell membrane, cytoplasm, organelles, and a nucleus containing DNA. The two main types of cells are prokaryotes and eukaryotes. Organelles in cells such as the endoplasmic reticulum, Golgi apparatus, lysosomes, mitochondria, and centrioles each have specific functions to support life processes within the cell.
Cell structure 2013
Plant and animal cells contain organelles that carry out essential functions. Key organelles include the nucleus, which controls cell activities, mitochondria which generate energy, and the cell membrane which regulates what enters and exits the cell. Plant cells additionally contain a cell wall, chloroplasts for photosynthesis, and larger vacuoles for storage. While organelles vary in shape and function, they work together within cells to keep organisms alive.
Cell
Plant and animal cells both contain a cell membrane, cytoplasm, and organelles like mitochondria and a nucleus. The key differences are that plant cells also contain a cell wall and chloroplasts, which allow them to perform photosynthesis using chlorophyll. The cell wall provides plant cells with structure and rigidity, while chloroplasts contain chlorophyll to store solar energy through photosynthesis.
Cell Structure 2013
Plant and animal cells share some common structures but also have distinct differences. Both contain organelles like the nucleus, mitochondria, endoplasmic reticulum, Golgi bodies, lysosomes, and cytoplasm that carry out basic cell functions. Plant cells additionally contain a cell wall, chloroplasts, and central vacuole not found in animal cells. The nucleus acts as the cell's control center while mitochondria generate energy and chloroplasts carry out photosynthesis in plant cells. Cell membranes envelop cells and regulate what enters and exits through selective permeability.

1. The cell is the fundamental unit of structure and function in all living organisms.
2. Cells come in a variety of shapes and sizes, and have a plasma membrane, cytoplasm, and organelles that allow them to carry out functions necessary for life.
3. Eukaryotic cells contain a nucleus and membrane-bound organelles, while prokaryotic cells like bacteria lack these structures.
Cell theory
Cells were first discovered in 1665 by Robert Hooke, who observed structures in cork under a microscope that resembled rooms of monks, which he called cells. The cell theory states that all living things are made of one or more cells, cells are the basic units of structure and function in organisms, and cells only come from preexisting cells. There are two main types of cells - prokaryotic cells which lack nuclei and have DNA throughout, and eukaryotic cells which have nuclei and membrane-bound organelles. Eukaryotic cells contain organelles that perform specific functions, and plant and animal cells contain both similar and different organelles such as chloroplasts in plant cells and lysosomes in animal cells. Cells work
Cells and tissues
Cells are the basic unit of structure and function in living organisms. The key components of cells include the nucleus, cytoplasm, cell membrane, and in plant cells cell walls, vacuoles, and plastids. Cells divide through mitosis to grow and reproduce. As cells become specialized through division of labor, they develop distinct shapes and chemical functions to perform roles like conducting nerve impulses, absorbing water and minerals in roots, moving mucus in the lungs, or transporting nutrients in plants. Tissues are groups of similar cells that work together, such as muscle or gland tissues. Organs are composed of multiple tissue types organized to perform a specific function, and organ systems integrate to keep the whole organism alive.
