Cell Structure Flashcards
What labels would you include when drawing a diagram of an animal cell?
Nucleus Cell membrane Cytoplasm Ribosome Mitochondria Temporary vacuole
What labels would you include when drawing a diagram of a plant cell?
Nucleus Cell membrane Cytoplasm Chloroplast Large vacuole Cell wall Mitochondria
Description and function of a cytoplasm?
Chemical reactions take place here
It is a complex mixture of structures, dissolved molecules and water
Description and function of a nucleus?
Controls the activities of the cell. Contains chromosomes which carry genetic information (genes).
It is the largest organelle.
Description and function of the cell surface membrane?
Controls what goes in and out of the cell; permits the entry of certain molecules.
It is a selectively permeable barrier between the internal an external environment of the cell.
Description and function of mitochondria?
It is the site of chemical reactions for respiration.
Cells with high energy demands (e.g. muscle cells) have more mitochondria
Description and function of the cell wall?
Provides structural support to plant cells and helps to maintain their shape.
Made of the carbohydrate cellulose.
Description and function of the vacuole?
Stores dissolved sugars, mineral ions and other solutes in a plant cell.
It is a membrane.
Description and function of a chloroplast?
The site of chemical reactions for photosynthesis.
Contains the green pigment chlorophyll, which absorbs light energy.
What is a fertilised egg cell called?
A zygote
What labels would you include when drawing a diagram of a sperm cell?
Why is its function?
Tail (flagela)
Chromosomes
To swim to the ovary and fertilise the egg for reproduction.
What is the level of organisation for the whole body (starting with cells)?
Cells ➡ Tissues ➡ Organs ➡ Organ systems ➡ Whole body
