Cells Make up Plants

What is the definition of a cell? The basic unit of life. Can you think of reasons why cells need nutrition and a good environment?

Definitions and plant cell parts.  Cytoplasm-gel like substance found in a cell  Chloroplasts-a green structure in a plant Cell Wall-a stiff covering that protects plant cells  Nucleus-control center of the cell  Chromosomes-provides direction for cell to follow  Endoplasmic Reticulum-transportation network  Mitochondrion-produces energy in the cell  Vacuole-cell storage sac for food, waste and water

Diffusion -movement of gases from higher concentrations to lower concentrations Passive Transport -materials do not need energy to move from higher concentration to lower to a lower concentration Active Transport -materials need energy to move from a higher concentration to lower concentration Osmosis -water moving from higher concentration to a lower concentration

Mitosis - cell division which forms 2 identical cells Meiosis -cell division where the resulting 4 cells have half the number of chromosomes needed for sexual reproduction How can one cell develop into a plant or animal?
