B1 : Animal and Plant cells Flashcards
Cell membrane
Controls what goes in and out of the cell
Ribosomes
The site of protein synthesis
Nucleus
Contains genetic material of the cell and controls the cell
Cytoplasm
Where chemical reactions take place
Mitochondria
Energy released from respiration
Chloroplast
The site of photosynthesis
Permanent Vacuole
Gives the cell structure and a store of sap
Cell wall
Gives the plant structure and support
Define eukaryotic
Cells such as animal and plant cells that contain genetic material in the nucleus
List the organelles found in an animal cell
Nucleus, Cell membrane, Ribosomes, Mitochondria and Cytoplasm
What is the function of the nucleus
To store genetic material
What is the function of the mitochondria
The site of aerobic respiration
What three cell structures are found only in plant cells and not in animal cells?
Cell wall, chloroplast, permanent vacuole
What structure is responsible for making proteins
Ribosomes
What is the role of chloroplasts
The site of photosynthesis, contains chlorophyll
Salivary cells produce amylase, which is a type of protein, what type of cell structure will they have a lot of?
Ribosomes
Why are muscle cells likely to have large number of mitochondria?
Muscles cells require more mitochondria because they this id where aerobic respiration occurs and transfers energy through the use of ATP by the muscles.
The root hair cell is a plant cell, but it has no chloroplasts why is it not considered an animal cell?
It contains no chloroplasts because it is underground and so receives no sun and so doesn’t require chloroplasts. It does contain all of the other factors that are present in plant cells.
Suggest why the nucleus and mitochondria are so important in all cells (4)
.The nucleus is important in all cells because the nucleus allows for the production of all proteins. It contains all of the genetic code that the body is created from
.Mitochondria is needed to allow the energy for a wide range of biological processes such as muscle contraction and movement
Compare a plant and animal cell (4)
Different shapes.
Different organelles, both have nucleus, cytoplasm, mitochondria, ribosomes and cell membranes. Both are responsible for protein synthesis for growth and repair.
