function and structure of cells

• for our exam, we have to label an animal cell with 4 labels
• The labels of an animal cell are: Nucleus, Cytoplasm, Cell Membrane, and mitochondria
• For our exam, we have to label a plant cell with 7 labels
• The labels of a plant cell are: Nucleus, Cytoplasm, Cell Membrane, Cell Wall, Vacuole, Chloroplasts, and Mitochondria
• In a plant cell, the cell membrane is inside the cell wall
• The plural of mitochondrion is mitochondria
• the long complex molecules inside the nucleus are called chromosomes
• what a cell is like and how it behaves is controlled by information held in it's chromosomes
• chromosomes are made up of genes
• substances are let in and out of cells by the cell membrane
• most chemical reactions in the cell take place in the cytoplasm
• chemical reactions in the cytoplasm are controlled by enzymes
• most of the energy that a cell uses is released in it's mitochondria
• mitochondria releases energy by respiration
• only plant cells have cell walls, chloroplasts and vacuoles
• cell walls are made up of cellulose
• cellulose in cell walls gives a plant support
• the support given given by cellulose in cell walls help a plant stay upright
• chloroplasts contain chlorophyll
• chlorophyll is needed for photosynthesis
• vacuoles contain cell sap
• the vacuole helps with storage and support
• plant cells get their support from their cellulose walls and vacuole
