Cell Biology Flashcards
The genetic material in a plant and animal is found in the?
Nucleus
What do both plant and animal cells have?
Membrane,Nucleus and a Cytoplasm
What are bacteria cells known as?
Eukaryotic Cells
What is the size of bacterial cells compared to animal cells?
It is enclosed in a nucleus
What is the cell wall of plants and algal cells made from?
Cellulose
What parts of plant cells that are not found in animal cells?
Chloroplast,Permanent vacuole
What is found in the permanent vacuole of a plant cell?
Cell Sap
What is the function of the nucleus?
The nucleus controls the activities of the cell and stores it DNA.
What is the function of a cytoplasm?
A cytoplasm is a liquid gel where most chemical reactions take place.
Whats the function of a cell membrane?
Controls the passage of substances in and out of the cell.
Whats the function of mitochondria?
Where anaerobic respiration takes place releasing energy for the cell
Whats the function of ribosomes?
Where protein synthesis takes place.
What is the function of chloroplasts?
Chloroplast contains chlorophyll which absorbs light so the plant can make food by photosynthesis.
What is the function of permanent vacuole?
Permanent vacuole is important it keeps the cells hard to support the plant.
What is the function of plasmids?
Where the genetic material is found in bacteria cells.
What is cell wall?
Made of celluose which strengthens the cell.
What is the function of plasmids?
Where some of the genetic material is found in bacterial cells?
Give a specialisation of a sperm cell?
A large nucleus containing genetic information.A long tail to assist with movement
Specialisation of nerve cell
A long axon to carry infomation over long distances.Able to pass information to neighbouring cells
Specialisation of a muscle cell
Contains mitochondria to transfer energy needed for contracting.
Specialisation of a root hair cell
Root hair increases the surface area for water uptake.Has a large vacuole to mantain water.
Where does the energy in active transport come from?
Respiration
