Biology

• What are all living things made of?

  They are made of cells.
• What cell are animal and plant cells?

  Eukaryotic since they are complex
• What cell Is a bacteria?

  Prokaryote since they are smaller and simpler
• What are eukaryotes?

  Organisms with cells that have a nucleus and membrane-bound organelles.
• What is a prokaryote?

  A prokaryote is a type of organism that lacks a nucleus and other membrane-bound organelles.
• explain nucleus

  The nucleus contains genetic material that controls the activities of the cell.Genetic material is arranged into chromosomes.
• What is a cytoplasm?

  A cytoplasm is a gel like substance where most of the chemical reactions happen.It contains enzyme that control these chemical reactions.
• Explain cell membrane

  Cell membrane holds the cell together and controls what goes in and out.
• Explain mitochondria

  Mitochondria is where most of the reactions for respiration take place.Respirarion transfers energy that the cell needs to work.
• Explain ribosomes

  These are involved in translation of genetic material in the synthesis of protein.
• State the subcellular structure most animal cells have

  Nucleus,Cytoplasm,Cell membrane, Mitochondria,Ribosomes.
• State the extra subcellular structures that animal cells have that animal cells don’t

  Rigid cell wall,Large vacuole,Chloroplasts.
• Explain the rigid cell wall

  The rigid cell wall is made of cellulose.It supports the cell and strengthens it.
• Explain large vacuole

  The large vacuole contains cell sap, a weak solution of sugar and salts.It contains the internal pressure to support the cell.
• Explain the chloroplasts

  In the chloroplasts is where photosynthesis occurs,which makes food for the plant. They contain a green substance called chlorophyll.
• State the subcellular structures of bacterial cells

  Chromosomal DNA,Ribosomes,Cell membrane,Plasmid DNA,Flagellum
