Random
True or false. Both prokaryotes and eukaryotes contain a cell membrane, cytoplasm, ribosomes, and DNA.
What is True
This property allows some things to enter/leave the cell, and blocks other things from doing so.
What is selective permeability?
This fills the space inside a cell. It is semi-fluid and is composed of water and dissolved materials.
What is cytoplasm?
This organelle provides the cell with the ATP it needs to perform its functions and activities. Known as the powerhouse of the cell.
What is the mitochondria?
This occurs when particles of a substance move from where there are many particles to where there are few particles. Going from high concentration to low concentration.
What is diffusion?
This organelle directs cell processes by providing DNA instructions. It is surrounded by its own membrane and is covered with pores.
What is the nucleus?
These structures are used for cell movement. The first is long and there are usually very few of them. The second are short and there are usually many of them.
What flagella and cilia?
Osmosis is the special name for the movement of this specific liquid across the cell membrane.
What is water?
This instrument contains a stage, light source, and eyepiece.
What are microscopes?
Large molecules that cannot pass through the phospholipid bilayer must pass through these.
What are transport proteins?
This organelle is a series of flattened membranes. Cell products pass through these membranes and become packaged for delivery in or out of the cell.
What is the Golgi apparatus?
This organelle digests worn out cell parts and also plays a role to defend the cell from infection. It deals with the waste.
What is a lysosome?
This occurs when water diffuses into a cell.
What is osmosis?
This cell type has no nucleus or other organelles. Bacteria are the only example of this cell type.
What is a prokaryotic cell?
The part of the cell membrane is hydrophobic
What are hydrophobic tails?
This organelle is a series of interconnected passageways. Proteins and lipids are synthesized (put together) here also. There are two varieties 'S' and 'R'.
What is the endoplasmic reticulum?
These are made by the nucleolus and their function is to follow DNA instructions to make stuff. They are free-floating or may be found attached to the ER.
What are ribosomes?
Spritzing perfume in one corner of a room until the scent naturally spreads across the whole room is an everyday example of this passive process.
What is Diffusion?
Because prokaryotes lack a nucleus, their circular DNA floats freely in this concentrated cytoplasmic region.
What is Nucleoid Region?
This green, pigment-filled organelle absorbs sunlight to carry out photosynthesis.
What is a chloroplast?
Found floating in the cytoplasm or attached to the rough ER, these tiny molecular machines build proteins.
What are ribosomes?
The three differences between plant and animal cells are:
1. Plant cells have cell walls. 2. Plant cells have chloroplasts 3. Animal cells have centrioles. 4. Plant cells have a large vacuole. 5. Plant cells consist of stacking
True or False: Passive diffusion and facilliated diffusion require energy?
No.
