Which characteristic of life is represented by plants performing photosynthesis?
What structure is found in all eukaryotic cells that deals with the production of energy?
Mitochondria
Which part of the scientific method involves making an educated guess about the outcome of the experiment?
Hypothesis
True or False: All organisms are made up of one or more cells.
True
Which organelle is responsible for autophagy?
Lysosome
A population of organisms ability to adapt to their environment over a LONG period of time, resulting in changes in DNA is known as:
Evolution
Which organelle is known as the recycling plant of eukaryotic cells?
Lysosome
Yes. New evidence can be found that may require a change to a scientific theory.
What scientific tool was crucial for the discovery that all living things are made of cells?
Microscope
True or False: The lysosome works closely with the vacuole. The lysosome sorts the damaged cells and decides what can be reused and what needs to go to the vacuole for disposal.
True
An organism's ability to maintain a stable internal environment regardless of changing external environment is known as:
Homeostasis
What is difference between a vacuole in plants and animals?
Size- Plant cells hold more food and water in their vacuole than animals so it is larger.
