Cell Structure Flashcards
Cell Membrane
Allows materials in and out of the cell, giving it some structure at the same time.
Ribosomes
The location where protein synthesis takes place.
Chloroplasts
Contains chlorophyll, which is where photosynthesis takes place.
Mitochondria
Where energy is released during respiration.
Nucleus
Where the DNA of the cell is contained.
Cell Wall
Supports the cell and keeps its shape. Found exclusively in Palisade cells.
Cytoplasm
Where many chemical reactions take place
Vacuole
Full of cell sap, that the cell can use for energy, and helps keeps the cells shape. Found exclusively in Palisade cells.
Root Hair Cell: Found in?
The roots of plants.
Root Hair Cell: Function?
To absorb nutrients and water from the soil and send it to the plant to be used.
Root Hair Cell: Design?
Has long, thin hairs to spread further so it can carry more nutrients. It has a very thin cell wall so water can pass.
Palisade Cell: Found in?
The top of leaves on a plant.
Palisade Cell: Function?
To carry out photosynthesis (this produces energy and food for the plant).
Palisade Cell: Design?
A lot of chloroplasts to make a lot of energy, and is on the top of the leaf, where most of the sun will shine on.
Ovum Cell: Found in?
Only in females; normally in the overies, sometimes in the fullopian tubes.
Ovum Cell: Function?
To be fertilised by a sperm cell and develop into a baby.
Ovum Cell: Design
Lots of mitochondria to create a lot of energy. The nucleus contains the mothers genes.
Red Blood Cell: Found in?
Inside of the circulatory system, and travels around the veins, capillaries and arteries.
Red Blood Cell: Function?
To collect oxygen from the lungs and carry it around the body to be used. It also collects carbon dioxide to be exhaled.
Red Blood Cell: Design?
Coated in a chemical called haemoglobin that oxygen sticks to. Has a biconcave shape that allows it to bend so it is harder for it to get stuck.
Sperm Cell: Found in?
Only in males, made in men’s testicles, and in sexual intercourse, is released from the penis.
Sperm Cell: Function?
To fertilise a female egg cell so it can develop into a foetus. Contains the fathers genes.
Sperm Cell: Design?
Has a flagellum (tail) for swimming, a lot mitochondria for swimming far, and a acrosome (cone) head full of enzymes that can digest the cell membrane of egg cells
Muscle Cell: Found in?
Makes up all of the muscles in our bodies.
Muscle Cell: Function?
Contracts to get shorter an relaxes to get longer.
Muscle Cell: Design?
Has a lot of mitochondria since it needs a lot of energy.
Nerve Cell: Found in?
All around our body, in our nervous systems.
Nerve Cell: Function?
Quickly sends and receives electrical signals to and from the brain and nervous system.
Nerve Cell: Design?
A long shape so it can send signals further, as well as a branched out top for the same purpose.
