Name 4 characteristics of the typical animal cell
Mitochondria
Nucleus (DNA)
Cilia
Ribosomes
Cell membrane
Cytoplasm
Membrane enclosed organelles
What are single felled organisms called?
Name 1 example
Unicellular organism.
-bacteria
-amoeba
-euglena
-yeast
-protoctists
-paramecium
Name 6 characteristics of the plant cell
Ribosome
Nucleus
Cell membrane
Cell wall
Vacuole
Cytoplasm
Chloroplast
Mitochondria
Where is genetic material stored? (DNA)
The nucleus
How many chromosomes does a human usually have
46
How is protein helpful towards your body
Name 2 reasons
Protein helps my body:
Repair cells
Makes new cells
What is protein made up of
Amino acids
What are ribosomes made of
(2)
Ribosomal proteins
Ribosomal RNA (rRNA)
What is the largest organelle in the cell?
The nucleus
What happens to a cell with no nucleus
Give an example of a cell in the human body without a nucleus
They are either dead or have a short lifespan
Red blood cell
What type of cells don’t have a nucleus
Prokaryotic cells
What do enzymes do
They control chemical reactions that take place in the cytoplasm
What are all cells surrounded by
A cell membrane
Is the membrane freely permeable or partially permeable.
Explain what it means
Partially permeable
It controlls what substance goes in and out of the cell
Is the cell wall freely permeable or partially permeable.
Explain what it means
Freely permeable
It allows all the substances to go in and out
Where is most of the energy from respiration released?
The mitochondria
Mitochondria is used in cells that require lots of energy in respiration
Give 3 examples of characteristics only ever found in plant cells
Cell wall
Permanent vacuole (animals can have temporary vacuoles)
Chloroplasts
What carbohydrate is the cell wall made up of
Cellulose
What is cellulose
A carbohydrate that makes up a cell walls
Why is it important for a plant to absorb water
Because when a plant abosrbs water, it goes into the vacuole which then expands and pushes outwards against the cell wall giving the plant support
Define porous
Accepts water
(Doesn’t reject water)
When do plants develop a vacuole
When they are mature and fully grown
What substance is held in the vacuole
Sap
(A watery substance)
