cell organelles Flashcards
nuclues
Control chemical reaction within the cytoplasm because the nucleus contains DNA. Stores information needed for cellular division
ribosomes
Ribosomes are the site of protein synthesis. Amino acids join together to form proteins
cell membrane
A flexible phospholipid bilayer that controls the entry and exit of substances. Protects and separates the cell from neighbouring cells and the external environment
mitochondria
Releases energy for the cell through the process of respiration
rough endoplasmic reticulum
Consists of ribosomes and therefore is the site for protein synthesis
Golgi body
packages proteins into vesicles for the secretion of the cell
lysosomes
break down materials that are taken into the cell or break down worn-out organelles
cell wall
protects the plant cell and maintains its shape and prevents excessive uptake of water
vacuoles
stores water, nutrients, metabolic wastes and toxins ready for their removal and also protects the rest of the cell
chloroplasts
The site of photosynthesis in plant cells. Light energy is converted into chemical energy and stored as carbohydrates
what organelles are found in plant cells but not animal cells
- cell wall
- vacuoles
- chloroplasts
smooth endoplasmic reticulum
transports proteins, synthesises lipids and assists in the manufacturing for the cell membrane
