Cell specialization in multicellular organisms allows for division of labor, where different cell types perform specific functions. Through differentiation, cells acquire specialized structures to become tissues like muscle and nerve cells. Tissues combine to form organs like the heart and lungs, and organ systems work together to carry out body functions. This organization allows multicellular organisms to perform complex life processes more efficiently than single-celled organisms.
Cell structure and cell organisation
Cell organisation in multicellular organisms occurs at multiple levels:
1) Cells combine to form tissues, tissues combine to form organs, organs combine to form systems, and systems combine to form whole organisms.
2) In animals, the main tissue types are epithelial, muscle, nerve, connective, and blood tissues. Epithelial tissues form protective barriers and glands. Muscle tissues enable movement. Nerve tissues transmit electrical signals. Connective tissues connect and support other tissues.
3) In plants, meristematic tissues are actively dividing cells that facilitate growth. Permanent tissues provide structure and include epidermal, ground, and vascular tissues. Epidermal tissues form outer layers, ground tissues include food

Plant cells have several key structures that distinguish them from animal cells. They are surrounded by a cell wall composed of cellulose and other materials that provides structural support and protection. Inside the cell wall is a cell membrane. Plant cells contain organelles such as a nucleus, chloroplasts, mitochondria, and a central vacuole. Chloroplasts are important for photosynthesis and contain chlorophyll. Specialized plant cells include parenchyma cells involved in photosynthesis and food production, sclerenchyma and collenchyma cells that provide support, and xylem and phloem cells responsible for transporting water and nutrients. The main functions of plant cells are photosynthesis, transport throughout the plant, and storage
Cell organelles
This document provides information on various cell organelles and their functions. It discusses the key organelles found in eukaryotic cells including the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, peroxisomes, plastids, vacuoles, and centrosomes. For each organelle, it provides details on their structure, role, and working within the cell. The nucleus controls all cell activity, mitochondria generate energy, the endoplasmic reticulum modifies and transports proteins, the Golgi apparatus packages molecules for secretion, lysosomes digest waste, peroxisomes break down fatty acids, plastids perform photosynthesis and store food, vacuoles isolate waste and
Cytoplasmic organelles
the presentation gives the structure, function, and electron microscopic image of the various cytoplasmic organelles. it also includes the clinical significance of various organelle damage.
The Cell
Cells are the smallest and fundamental units of life. There are two main types of cells - prokaryotic cells, which are microscopic and consist of a single cell, and eukaryotic cells, which have more complex structures. Plant and animal cells contain similar organelles but also have some differences. Plant cells contain chloroplasts for photosynthesis and a cell wall, while animal cells lack these structures. Both cell types contain a nucleus, mitochondria, endoplasmic reticulum, Golgi bodies, and ribosomes that allow the cell to carry out essential functions.
Cell-Basic Unit of Life
This document discusses the parts of plant and animal cells. It defines a cell as the smallest unit of life and notes there are two main types - prokaryotic and eukaryotic cells. It then lists and describes the major organelles found in plant cells, such as the cell wall, chloroplast, cytoplasm, mitochondria, endoplasmic reticulum, nucleus, vacuole, lysosomes, Golgi complex and ribosomes. A similar list is then provided for the organelles commonly found in animal cells.
cell
Mitochondria can be found most in sperm cell because mitochondria produces ATP which provides energy for cell activities including cell motility. Sperm cells require a lot of energy for their movement and motility to fertilize the egg cell.

- Albert showed symptoms like diarrhea after drinking milk due to lactose intolerance, which is the inability to digest the sugar lactose found in milk.
- His mother should prepare breakfasts without lactose, such as orange juice, bread, boiled egg, and salad to prevent these symptoms.
- If Albert drank yogurt, he would likely not experience symptoms since the lactose has been pre-digested by microorganisms in the yogurt.

The document discusses the El Niño phenomenon and its effects on ecosystems. It provides background on El Niño, noting that it involves anomalously warm ocean temperatures off the coast of South America that disrupt typical weather patterns across the Pacific. The effects on ecosystems include changes in temperature, precipitation, currents and ocean temperatures that can lead to droughts, floods, fires, famine and disease outbreaks. Suggested measures to minimize impacts include enforcement of open burning laws, awareness campaigns on water conservation, cloud seeding, building water reserves, installing air filtration systems on factories, and educating the public.
