1 - variety and characteristics

• mitochondria are responsible for respiration and energy production within cells
• the cytoplasm is where most chemical reactions take place, it also contains organelles such as mitochondria and ribosomes.
• the nucleus contains the genetic material (DNA) which controls all cell activities
• ribosomes are where proteins are made from amino acids
• the nucleus is the control centre of the cell, it contains genetic material (DNA) which controls all activities that take place inside the cell.
• ribosomes are made up of proteins and RNA molecules that synthesise proteins from amino acids
• chloroplasts contain chlorophyll which absorbs light to produce glucose through photosynthesis
• ribosomes are the site of protein synthesis
• vacuoles store water, waste products or pigments
• chloroplasts contain chlorophyll and are found in plant cells only. They absorb light energy to make glucose during photosynthesis
• chloroplasts contain chlorophyll and are found in plant cells only. They absorb light to make glucose through photosynthesis
• chloroplasts contain chlorophyll which absorbs light to make glucose during photosynthesis
• cell membrane regulates what enters or leaves the cell by selective permeability
• cell membranes control what enters and leaves the cell by selective permeability
• cell walls give plant cells structure and support
• selectively permeable means only certain substances can pass through the membrane
• mitochondria convert energy stored in food into ATP by aerobic respiration
• mitochondria are responsible for respiration and energy production
• cell membrane regulates what enters/leaves the cell
