Living Environment Unit 1-3 Review

Which structures are listed in order from the least complex to the most complex?

• plant cell, leaf, chloroplast, rose bush

• chloroplast, plant cell, leaf, rose bush

• chloroplast, leaf, plant cell, rose bush

• rose bush, leaf, plant cell, chloroplast

The data table below shows the presence or absence of DNA in four different cell organelles Information in the table suggests that DNA functions

• within cytoplasm and outside the cell membrane

• both inside and outside the nucleus

• only within energy-releasing structures

• within cell vacuoles

Which organelle is correctly paired with its specific function?

• cell membrane -- storage of heredity information

• chloroplast -- transport of materials

• ribosome -- synthesis of proteins

• vacuole -- production of ATP

Which instrument was used in the 18th and 19th centuries and helped scientists develop the cell theory?

• electron microscope

• light microscope

• micro dissecting apparatus

• ultracentrifuge

Which activity might lead to damage of a microscope and specimen?

• cleaning the ocular and objectives with lens paper

• focusing with low power first before moving the high power into position

• using the coarse adjustment to focus the specimen under high power

• adjusting the diaphragm to obtain more light under high power

Which observation could lead to the conclusion that an object is non-living?

• it passes on hereditary information only through asexual reproduction

• it carries out synthesis

• it cannot perform metabolic processes

• it is composed of a cell, but does not have tissues

One characteristic of all living things is that they

• develop organ systems

• produce identical offspring

• maintain internal stability

• synthesize only inorganic matter

The ability to grow in size is characteristic of living organisms. Although an icicle may grow in size over time, it is considered nonliving because there is

• an increase in matter, but no increase in the number of icicles

• an interaction between the icicle and the environment

• no way for the icicle to move away from heat

• no metabolic activity present

Living organisms can best be distinguished from nonliving things by determining the presence or absence of

• carbon atoms

• oxygen atoms

• metabolic activities

• chemical reactions

Viruses are exceptions to the cell theory, but they have some characteristics of living things. What is one of these characteristics?

• They are made up of many specialized cells.

• They contain genetic material.

• They reproduce by mitosis.

• They contain chlorophyll.
