Cells structure and tissues BTEC level 2

What do you need to know?

Can you label the different parts of the cell?

cell membrane mitochondrion nucleus cytoplasm Label this typical animal cell with the following structures: cell membrane mitochondrion nucleus cytoplasm cytoplasm nucleus cell membrane mitochondrion

Label this typical plant cell with the following structures: cell membrane mitochondrion chloroplast  vacuole nucleus cytoplasm cell wall mitochondrion cytoplasm chloroplast vacuole nucleus cell membrane cell wall

What does each part of the cell do? Use the information on page 10 to complete your table

Plant Cells v Animal Cells Plants and animals consist of different types of cell that work together. Animal and plant cells have certain structures in common. Many cells are specialised and are adapted for their function. Use the pictures on p10 to make a table of what they have the same / what is different

answers Differences Plant cells have a vacuole Plant cells have chloroplasts Plant cells have a cell wall Similarities They have a nucleus They have cytoplasm They have a cell membrane

What do all the parts do? Structure Function Cytoplasm Where most of the chemical reactions happen Nucleus Contains genetic material which controls the cell’s activities Cell membrane Controls the movement of substances in and out of the cell Mitochondria Where most energy is released in respiration

plant cells only Structure Function Chloroplasts Absorb light energy for photosynthesis Cell wall Strengthens the cell and supports the plant Permanent vacuole Filled with cell sap to help keep the cell turgid Complete task 2 in your booklet

Quick quiz! Which cell part carries out each of these functions? •Gives the cell strength and shape •Controls cell activity •Encloses the cell, partially permeable •Sites of aerobic respiration •Contains cell sap and supports the cell •Chemical reactions take place here •Sites of photosynthesis
