Plant cells have these structures made of cellulose, while fungal cells have them made of chitin. Name the structure.
Cell wall
100
This type of water movement occurs across membranes due to solute concentration differences, and can be facilitated by specialized proteins called aquaporins.
osmosis

What is the structure highlighted in blue?
Pili

Unlike most eukaryotic cells, which type of blood cell loses its nucleus during development to maximize space for oxygen transport?
Red blood cells
200
Which large organelles, primarily used for storage and maintaining cell rigidity, are prominent in plant cells but much smaller or absent in animal cells?
Vacuoles
200
This process allows oxygen and carbon dioxide molecules to move directly through phospholipid bilayers without the use of energy.
simple diffusion
300
What is the structure highlighted in red?
Endoplasmic reticulum
300
Which long, multinucleated cells are found in vertebrates and are specialized for contraction?
Skeletal muscle cells
300
Which organelles, found only in plant cells and some protists, enable photosynthesis by converting light energy into chemical energy?
chloroplasts
300
These proteins enable the selective permeability of membranes by allowing specific ions to pass through when open, but block them when closed.
channel proteins?
400
What is the structure highlighted in purple?
Golgi apparatus
400
While most eukaryotic cells have one nucleus, this fungal structure and this muscle tissue both share the characteristic of being multinucleated. Name both.
What are aseptate fungal hyphae and skeletal muscle fibers?
400
animal cells have these structures for movement, such as in sperm cells, but they are rarely found in plant or fungal cells.
flagella
400
These proteins use ATP to move particles across membranes against a concentration gradient, enabling active transport.
pump proteins
500
What is the structure highlighted in blue?
(large central) vacuole
500
Which type of plant cell has no nucleus or organelles when mature and relies on companion cells for metabolic functions?
phloem sieve tube elements
500
Which structures, which organize microtubules during cell division, are present in animal cells but absent in most plant and fungal cells?
centrioles
500
This type of diffusion requires channel proteins, allowing ions to pass down their concentration gradient, but no energy is used.
facilitated diffusion
