GCSE AQA foundation Biology
Nucleus - Answer An organelle thontrol center of the cell. Contains DNA.
chloroplasts - Answer An organelle that captures energy from sunlight and use it for
photosynthesis.
vaccuole - Answer Organelle that contains liquid which keeps the plant hydrated.
Cell wall - Answer An organelle with a strong, supporting layer that protects the cells
and goes around the cell membrane in plant cells.
Cell membrane - Answer A organelle that controls which substances can enter or leave
the cell.
Cytoplasm - Answer The portion of the cell outside the nucleus where chemical
processes take place.
Mitochondria - Answer This organelle produces energy for the cell during respiration
Ribosome - Answer Organelle that is the site of protein synthesis
Chlorophyll - Answer Green pigment in plants found in chloroplasts that absorbs light
energy used to carry out photosynthesis.
Cell structures in a plant cell - Answer -Nucleus
-Cell membrane
-vacuole
-cell membrane
-chloroplasts
-cytoplasm
-mitochondria
-cell wall
-ribosomes
cell structures in a animal cell - Answer -Nucleus
-cell membrane
-cytoplasm
-mitochondria
-ribosomes
structures of a red blood cell - Answer -Biconcave shape (large surface area)
-Cell membrane
-Cytoplasm
Function of a red blood cell - Answer They take oxygen to all cells in the body.
, GCSE AQA foundation Biology
How are red blood cells specialised ? - Answer -Large surface area that allows
absorption of oxygen.
-Biconcave shape creates the large surface area for absorption of oxygen.
-They are able to fold to travel through the capillaries.
Structures of a sperm cell - Answer -Head contains the nucleus (DNA)
-The middle section contains Mitochondria
-Flagellum on tail.
Function of a sperm cell - Answer To fertilise eggs (ova) during sex.
How are Sperm cells specialised to their function? - Answer -The mitochondria gives it
energy to swim.
-The long tail with a slender flagellum allows the sperm to swim.
-The streamlined head makes swimming faster.
-The head contains enzymes which allows the sperm to digest the cell membrane of the
ova.
plasmids - Answer Circular DNA molecules that can replicate independently of the main
chromosomes of bacteria
prokaryotic - Answer unicellular organisms that do not have a nucleus e.g bacteria cell
eukaryotic - Answer Multicelluar organisms that have a nucleus
structures of a bacteria cell - Answer prokaryotic cell that contains plasmids,
chromosomal DNA, cytoplasm, a flagella, cell wall and a cell membrane
How are bacteria cells specialised? - Answer Most structures are general. The flagella
helps it move around.
-Cytoplasm contains enzymes for chemical reactions e.g respiration
Function of bacteria cell - Answer General function is to build up the immune system.
Structure of a yeast cell - Answer prokaryotic cell that has a cell membrane, cell wall,
nucleus, non-permanent vacuole.
Function of yeast cell - Answer To produce yeast needed in fermentation
How are yeast cells specialised? - Answer cytoplasm-site of anaerobic respiration.
NP vaccuole-keeps the cell hydrated during fermentation.
Diffusion - Answer Molecules move from an area of high concentration to an area low
concentration. It is a passive process, meaning no energy is required.
Examples of diffusion - Answer -diffusion of perfume.
