biology

• Mitochondria are the powerhouses of the cell, responsible for generating energy through cellular respiration.
• there are 46 chromosomes(23 pairs) in a human cell
• an egg cell has 23 chromosomes and a sperm cell has 23 which makes 46 when joined (23 pairs)
• a gamete is a reproductive cell
• sexual reproduction needs a male and female reproductive cell to produce offspring
• human cells only have a cell membrane and no cell wall
• the cytoplasm is a gel-like liquid that fills the inside of the cell
• the mitochondria is the powerhouse of a cell
• the Golgi apparatus transports, sorts and modifies protein and lipid
• the nucleus holds all the genetic material
• the DNA is stored in the chromosomes of a cell and holds genes
• lysosomes get rid of the waste products of the cell and are also involved in the digestion of bacteria
• asexual reproduction uses one cell from a parent to make offspring
• children of asexual reproduction are identical to their parent
• sexual reproduction creates an offspring with completely unique genes
• in sexual reproduction, two cells fuse together to form a zygote which contains half its dna from both parents
• a gene is a section of dna that codes for a protein or part of it
• meiosis is a type of cell division that produces four daughter cells from one parent cell
• mitosis is the process of cell division that results in two identical daughter cells
• budding and binary fission are two types of asexual reproduction
• binary fission involves the splitting of a single cell into two identical daughter cells
• budding occurs when a new organism grows out of a bud on the surface of another organism
• zygotes contain genetic information from both parents
• zygotes contain genetic information from both parents
• plant gametes are pollen and eggs
• reproduction is the production of offspring
• the process by which an egg develops into an embryo is called fertilisation
• plant cells have a cell membrane and a cell wall
• prokaryote cells do NOT have their DNA stored in a nucleus
• eukaryote cells have their DNA stored in the nucleus
• organelles are tiny structures within a cell that perform specific functions
• a prokaryotic cell has no organelles
• an eukaryotic cell does have organelles
