Get Readworks The Cells That Make Us Answer Key

Conclusion. Tissues are communities of cells that have functions beyond what any single cell type could accomplish. Healthy tissues require the proper mix of cells, and the cells within them must be oriented correctly and dividing at an appropriate rate.

Cells are the smallest structural and functional units of an organism, which are characteristically microscopic. Tissues are clusters of cells, specialized cells. Found in both unicellular and multicellular organisms. Found only in multicellular organisms.

Therefore, the answer choice that best defines a tissue is given by answer choice (B): a group of similar cells that work together to carry out a particular function.

How does Mike's mom compare the nuclear membrane and the cell membrane? Both the cell membrane and nuclear membrane are protective coverings. The cell membrane is like a blanket, while the nuclear membrane is like a sieve.

Your body is made of cells and when groups of cells do the same kind of work, they are called tissues. You have four main types of tissues: Connective, Epithelial, Muscle, and Nervous tissue. Connective tissue joins bones and cushions organs. Epithelial tissue covers the outside of the body.

Tissue is a group of cells or fluid that work together to perform a specific job in the body like cells in an organ like the kidney or heart or blood cells that carry oxygen to and waste materials from the cells in the body.

(TIH-shoo) A group or layer of cells that work together to perform a specific function.

Mike's mom replied, "Everything in our body is made of small units called cells. Think of it this way. Just like hundreds of thousands of bricks form a house, millions of cells form our muscles, bones, skin, and hair-eventually coming together to form the human body."
