biology

• Mitochondria produce energy through aerobic respiration.
• Chromosomes are made up of genes that determine characteristics such as eye colour or height.
• Chloroplasts are found only in plant cells, algae, and some protists.
• The thylakoid membrane is the site where photosynthesis occurs.
• Photosystem II (PSII) absorbs light energy from chlorophyll to split water molecules into oxygen and hydrogen ions.
• The nucleus contains the genetic material (DNA) which controls all cell activities, including growth and reproduction.
• Cell membranes control what enters and exits cells.
• Ribosomes are responsible for protein synthesis.
• The nucleus is the control centre of the cell where DNA is stored.
• Vacuoles store water, waste products, pigments, and enzymes involved in digestion.
• Light-dependent reactions occur in the thylakoids.
• Vacuoles store waste products or food reserves.
• Chloroplasts contain chlorophyll and carry out photosynthesis.
• Chloroplasts contain chlorophyll, which absorbs light energy to produce glucose through photosynthesis.
• Chloroplasts contain chlorophyll and carry out photosynthesis.
