What cells do you need to know for GCSE?
Animals are made up of cells. These cells are eukaryotic ….Animal cells.
| Cell structure | How it is related to its function. |
|---|---|
| Mitochondria | Organelles that contains the enzymes for respiration, and where most energy is released in respiration. |
| Ribosomes | Tiny structures where protein synthesis occurs. |
What are cells BBC Bitesize?
Cells are the smallest unit of life and the building blocks for all organisms. Each component of a cell has its own function. Nucleus, cell membrane, cytoplasm and mitochondria are four cell components that are found in both animal and plant cells.
What is a lysosome GCSE?
Lysosomes – Little Enzyme Packages You will find organelles called lysosomes in nearly every animal-like eukaryotic cell. Lysosomes hold enzymes that were created by the cell. The purpose of the lysosome is to digest things. They might be used to digest food or break down the cell when it dies.
What are ribosomes BBC Bitesize?
Ribosomes. Tiny structures where protein synthesis occurs. Most cells are specialised and are adapted for their function. Animals and plants therefore consist of many different types of cell working together.
What is a cell wall GCSE?
Cell wall. Made from cellulose fibres and strengthens the cell and supports the plant. Permanent vacuole. Filled with cell sap to help keep the cell turgid. Animal cells may also have vacuoles, but these are small and temporary.
What are bio cells?
A biological cell is a membrane-bound structure that occurs as a functional independent unit of life (such as in unicellular organisms, e.g. bacteria, protozoa, etc.), or as the structural or fundamental unit in a biological tissue specialized to perform a particular function in multicellular organisms (e.g. plants and …
What is a chloroplast BBC Bitesize?
Function. Chloroplast. Organelles that contains the green pigment, chlorophyll, which absorbs light energy for photosynthesis. Contains the enzymes needed for photosynthesis.
What is biology BBC Bitesize?
Biology is the study of living organisms and their structure, life-cycles, adaptations and environment.
What is a cytoplasm GCSE?
Cytoplasm. A jelly-like material that contains dissolved nutrients and salts and structures called organelles. It is where many of the chemical reactions happen. Nucleus.
What do ribosomes do GCSE?
Ribosomes: Ribosomes make proteins for the cell. Cell Membrane: This holds the cell together and controls what goes in and out of the cell.
Do animal cells have vacuoles GCSE?
Animal cells may also have vacuoles, but these are small and temporary. In animals, they are commonly used to store or transport substances.
What are plant cells GCSE?
Plants are made up of cells. These cells are eukaryotic . This means they have a nucleus and other structures which are surrounded by membranes . A generalised plant cell and its components.
What is the structure of a cell?
A jelly-like material that contains dissolved nutrients and salts and structures called organelles. It is where many of the chemical reactions happen. Contains genetic material, including DNA, which controls the cell’s activities.
What is a cell?
Tiny structures where protein synthesis occurs. Most cells are specialised and are adapted for their function. Animals and plants therefore consist of many different types of cell working together.
What are the characteristics of bacterial cells?
Bacterial cells. Bacteria are all single-celled. The cells are all prokaryotic. This means they do not have a nucleus or any other structures which are surrounded by membranes. Larger bacterial cells may be visible using a light microscope, however an electron microscope would be needed to see the details of the cell organelles.
What are the two parts of a bacterial cell?
These include the cytoplasm and cell membrane. Bacteria have other components that are unique: The DNA of bacterial cells is found loose in the cytoplasm. It is called chromosomal DNA and is not contained within a nucleus. Bacteria also have small, closed-circles of DNA called plasmids present in their cytoplasm.
