Cell Structure
Akopọ
Cut a thin slice of any plant or animal under a microscope and you see the same thing: thousands of tiny, box-like units called cells. Cells are the building blocks of every living thing, and each part inside a cell has a specific job, from the nucleus that controls the cell to the mitochondria that release its energy.
In this lesson you will compare plant, animal and bacterial cells, learn what each structure does, and see how some cells are specially shaped for one task. You will also learn how cells build up into tissues, organs, organ systems and finally the whole organism.
Awọn Afojusun
- Describe and compare the structure of a plant cell with an animal cell, limited to: cell wall, cell membrane, nucleus, cytoplasm, chloroplasts, ribosomes, mitochondria, vacuoles
- Describe the structure of a bacterial cell, limited to: cell wall, cell membrane, cytoplasm, ribosomes, circular DNA, plasmids
- Identify the cell structures listed in
- Describe the functions of the structures listed in
- State that new cells are produced by division of existing cells
- State that specialised cells have specific functions, limited to: (a) ciliated cells - movement of mucus in the trachea and bronchi (b) root hair cells - absorption (c) palisade mesophyll cells - photosynthesis (d) neurones - conduction of electrical impulses (e) red blood cells - transport of oxygen (f) sperm and egg cells (gametes) - reproduction
- Describe the meaning of the terms: cell, tissue, organ, organ system and organism as illustrated by examples given in the syllabus
