6th Grade Midterm Study Guide

Humans start from a single cell. Eventually, as cells divide, they start to differentiate, or specialize. Some cells are specialized for movement of the human body. What type cells would these be?

• muscle cells

• nerve cells

• bone cells

• skin cells

Which of the following is true regarding cell type and cytoplasm?

• Prokaryotic cells have cytoplasm and eukaryotic cells do not.

• Eukaryotic cells have cytoplasm and prokaryotic cells do not.

• Neither prokaryotic nor eukaryotic cells have cytoplasm.

• Prokaryotic and eukaryotic cells have cytoplasm.

In the above diagram, which cell structure is responsible for taking in and breaking down foreign particles and damaged organelles?

• ribosome

• cell membrane

• lysosome

• mitochondria

How do prokaryotic cells reproduce?

• only asexually

• only sexually

• usually asexually and sometimes sexually

• usually sexually and sometimes asexually

Which organelle helps digest material in cells?

• Golgi bodies

• vacuoles

• endoplasmic reticulum

• lysosomes

Tissues are made up of a group of similar cells. The advantage of this type of organization is that the cells that make up a tissue:

• are coordinated to carry out one type of job.

• can do very different jobs at the same time.

• don't need any energy if they are part of an organ.

• don't need to have a nucleus or cytoplasm.

Unlike prokaryotic cells, eukaryotic cells have ________________.

• an external membrane

• internal membranes

• DNA

• a cell wall

All organisms consist of _____________.

• one or more cells

• only one cell

• more than one cell

• something other than cells

What separates the cytoplasm of eukaryotic cells from most of the organelles?

• the cell membrane

• the cell wall

• the organelle's membrane

• the organelle's wall

Which organelle serves as a storage space in a cell?

• Golgi body

• vacuole

• endoplasmic reticulum

• lysosome
