1.1 Cell Structure N5 Biology

Question 1

state the cell structures found in the animal cell

Answer 1

the cell structures found in animal cells are the nucleus, cytoplasm, cell membrane, mitochondria and ribisomes

Question 2

state the cell structures found in the plants cell

Answer 2

the cell structures found in the plant cell are the nucleus, cytopplasm, chloroplasts, mitochondria, ribisomes, vacoule, cell membrane, cell wall

Question 3

explain the purposes of the cell structures nucleus, cytoplasm, cell membrane, Ribisomes

Answer 3

Nucleus: controls cell activity

Cytplasm: jelly like fluid where all organelles are found and in which many chemical reactions take place

cell membrane: controls exit and entry of substances in and out of the cell

Ribisomes: (small circular structures in the cytoplasm or attached to membranes inside the cell) which are the site of protein synthesis

Question 4

describe the purpose of the cellstructures mitochondria, cell wall, chloroplasts, vacoule,

Answer 4

Mitochondria: (oval structures inner folded membrane) which are the site of aerobic respiration

Cell wall: (surrounding cell membrane) which is made of cellulose and provides support to the plant cell

Chloroplasts:(oval green structures) which are the site of photosynthesis

vacoule: (large mis-shaped structure) which contains cell sap and is involved in cell support

Question 5

what are cells measured in

Answer 5

cells are measured in micrometers

Question 6

how many micrometers are in

1cm

Answer 6

there are 1000 micrometers in 1cm

Question 7

what type of organelles are found in a fungal cell

Answer 7

the type of organelles found in a fungal cell are the nucleus, Cytoplasm, Cell membrane, Cell wall, Ribosomes. Mitochondria and Vacoule

Question 8

what are organelles found in a typical bacterial cell

Answer 8
