Characteristics of Life
An individual plant, animal, or single-celled life form.
What is an organism?
The two parts of the microscope that you should hold on to whenever you're carrying it from one place to another.
What is the neck and the base.
The outer boundary of the cell that allows food to enter and waste to exit.
What is the cell membrane?
The function of xylem in a plant is to _____.
transport water to all cells of the plant
All living things respond to this.
What is stimuli?
A thing or event that evokes a specific functional reaction in an organ or tissue.
What is a stimulus?
Bacteria reproduces using _____.
asexual reproduction.
The fluid substance containing the organelles. It lies between the nucleus and the cell membrane.
What is the cytoplasm?
True or False:
All living things do not perform aerobic cellular respiration.
False.
All living things perform aerobic cellular respiration.
All living things exchange these.
What are gases?
The process by which water flows through plants, entering the roots and exiting the stomata .
What is transpiration?
A student saw something moving on the floor and exclaimed, “It’s alive!” Write an argument that includes evidence and explains why you agree or disagree with this student.
Movement is not a characteristic of all living things. You cannot use movement to determine for sure if something is living because some nonliving things can move, and many living things do not move from place to place.
A semirigid structure that surrounds cells of plants, fungi, and bacteria.
What is a cell wall?
What does aerobic cellular respiration do?
It turns glucose into usable energy in cells.
All living things get bigger, or do this.
What is grow?
This is the white, starchy part of a flowering plant seed and contains food to nourish the embryo during germination.

What is the most significant difference between bacteria and eukaryotic cells?

All organisms carry out all the functions of life. Explain the difference in how multicellular and single-celled organisms do this.
Multicellular organisms:
1. Use systems of organs to carry out the functions of life.
2. Individual cells in multicellular organisms cannot survive on their own.
Single-celled organisms:
1.Carry out all of the necessary functions on their own.
2.They depend on cell structures and organelles to carry out all life functions.
These organelles convert the chemical energy of food into a form that the cell can use.
What is mitochondria.
Two things that a plant cell has that animal cells do not.
What is a cell wall and chloroplasts?
