Biology- organelles

what is endoplasmic reticulum (ER)

• membrane bound organelle

• attached to nucleus

• smooth- no ribosomes- stores lipids

• rough- ribosomes- stores proteins

Golgi apparatus/ body

• membrane bound organelle

• organising, modifying and secreting lipids and proteins

• stack of membranes

• package into vesiculas

chloroplast

• only found in plants and bacteria

• photosynthesis - carbon+water=sugar+oxygen

• chlorophyl is what makes it green

Cell wall

• only in plant cells, bacteria and fungi

• provides structure and support and protection

Cytoplasm

• jelly-like substance

• mostly made of water

• some reaction occurs here

Nucleus

• membrane bound organelle

• stores genetic information

• controls cell function

cell membrane

• made of lipid bi-layer

• controls movement of substance in and out of cell (semi-permeable)

mitochondria

• membrane bound organelle

• involved in energy production

• sight of aerobic respiration

Ribosomes

• site of protein synthesis

• produce protein

vesicle

• transport vessel for golgi body

• delivers substances around cell

vacuole

• stores water and salts

• plants have one large one

• animals have multiple little ones

• breaks down waste

what is ATP

ATP is made by converting the food we eat into energy.

• cellular respiration

• when converted into ADP+pi is active transport
