- Eukaryotic Cells
- Ribosomes
- Floats free in cytoplasm of attached to ER
- Made up of proteins and RNA
- Not surrounded by a membrane
- Where proteins are made
- Plasma Membrane
- Found on surface of animal cells and in cell wall of plants
- Made of lipids and proteins
- Regulates movement of substances in and out of the cell
- Has receptor molecules
- Cell Wall
- Surrounds plant cells
- Made of cellulose
- Supports plant cells
- Nucleus
- Surrounded by nuclear envelope
- Contains chromatin and nucleolus
- Controls cell's activities
- Contains instructions to make proteins
- Pores in envelope allow for substances to pass in and out
- Nucleolus makes ribosome
- Lysosome
- Surrounded by a membrane
- Contains digestive enzymes
- Can digest invading cells or break down worn out components of the cell
- Rough Endoplasmic Reticulum
- System of membranes enclosing a fluid-filled space
- Studded with ribosomes
- Folds and processes proteins
- Smooth Endoplasmic Reticulum
- Similar structure to rough ER but with no ribsomes
- Synthesises lipids and carbohydrates
- Vesicle
- Fluid-filled sac in cytoplasm
- Surrounded by a membrane
- Transports substances in and out of the cell and between organelles
- Some formed by golgi apparatus or ER, others at cell surface
- Golgi Apparatus
- Group of fluid-filled, membrane bound flattened sacs
- Processes and packages proteins and lipids
- Makes lysosomes
- Mitochondria
- Have a double membrane, the inner one is folded to form cristae
- Matrix contains enzymes used in respiration
- Site of aerobic respiration
- Chloroplast
- Found in plant cells
- Surrounded by a double membrane and also has membranes called thylakoid membranes
- Thylakoid membranes for grana
- Site of photosynthesis
- Centriole
- Small, hollow cylinders made of microtubules
- Found in animal cells and some plant cells
- Involved in separation of chromosomes during cell division
- Cilia
- Hair-like structures found on surface of some animal cells
- Have a ring of 9 pairs of protein microtubules, with two in the middle
- Moves substances along cell surface
- Flagellum
- Stick out from cell surface
- Propel cells forward
- Ribosomes
