Which statement would most likely be found in an article about multi-celled organisms like plants?

Plants contain many specialized cells that perform different functions.

Plants have a simple structure.

Plants contain only one cell that performs all functions.

Plants do not need to eat, remove waste, or reproduce.

How are single-celled organisms and multi-celled organisms similar?

Both need food for energy and growth.

Both have a skeletal system for support.

Both require the interaction of many cells to survive.

Both are able to carry out all life functions in only one cell.

How are multi-celled and single-celled organisms different?

Multi-celled organisms have large numbers of specialized cells to perform a variety of life functions, while single-celled organisms complete life functions with one cell.

Multi-celled organisms need energy to survive, while single-celled organisms need no energy to survive.

Single-celled organisms can be seen without using a microscope, while multi-celled organisms are microscopic.

Single-celled organisms have large numbers of identical cells that all perform the same function, while multi-celled organisms have cells that are all different and perform different life functions.

Fungi and bacteria are both single-celled organisms. What do they most likely have in common?

Both fungi and bacteria can carry out all life functions in their one cell.

Both fungi and bacteria are large organisms.

Both fungi and bacteria need sunlight and nutrients from the soil to be able to grow.

Both fungi and bacteria are highly specialized to do only one job so they must work with other cells to obtain food.

Which best explains why both cats and humans are multicellular organisms?

They need many cells working together to meet their basic needs.

They get energy from many food sources.

They get energy from a single food source.

They need only one cell to meet their basic needs.

Which is a difference between frogs and bacteria?

Frogs are multi-celled organisms, while bacteria are single-celled organisms.

Frogs are able to control all life processes in one cell, while bacteria cannot.

Frogs are single-celled organisms, while bacteria are multi-celled organisms.

Frogs must rely on other single-celled organisms for survival, while bacteria are dependent only on themselves.

A scientist is trying to decide whether an organism is unicellular or multicellular. Which information would help the scientist most to make her decision?

how many types of cells are in the organism

size of the cells of the organism

Which of the following is true about prokaryotic and eukaryotic organisms?

Eukaryotic organisms can be unicellular or multicellular.

Prokaryotic organisms can be unicellular or multicellular.

All unicellular organisms are eukaryotic

All multicellular organisms are prokaryotic

How can the cytoskeleton of a cell be described?

A framework and anchor for organelles

Selectively permeable series of membranes

when molecules move from a high concentration to a low.

simple, mostly single-celled organism that lacks a nucleus, or any other membrane-bound organelle.

have a peptidoglycan cell wall and many have polysaccharide capsules.

have a true nucleus, which means the cell's DNA is surrounded by a membrane.

contain membrane-bound organelles, such as the nucleus
