BioNow Student Study Guide: Cell Division Part I: Pre-Video Questions 1) Provide a brief definition of the following terms to gain familiarity before watching the video. a. Cell division: b. Cell cycle: c. Mitosis: d. Cell differentiation: e. Hormone: f. Gene expression: g. Shoot system: h. Root system: i. Asexual reproduction: j. Habitat restoration: Please read the video summary below and answer the questions that follow in detail. Do you picture science as something that is only done by scientists or students in a science class? In reality, methods of science can be used by anyone and anywhere to solve problems. Have you ever looked for a solution to a problem by comparing different options and choosing the best? If yes, then you have practiced science. The purpose of this experiment is to restore a habitat by finding a cheap and easy way to grow new plants. When you hear the word grow, you should think of cell division. Any organism, including you, grows, repairs damage, and replaces old cells through the process of cell division. For new plants to grow, they will need to produce new cells and control what the cells become, such as leaves, stems, or roots. That is the process of cell differentiation, where a new cell becomes a specific type of cell based on signals it receives during development. Science is based on questions to answer and problems to solve, not just remembering facts. While learning terms and processes is a necessary part of science, this experiment shows how they integrate into the real purpose of science—to solve problems. 2) Describe a time when you used a scientific approach to solve a problem. 3) Is it worthwhile to spend time and large sums of money to restore damaged habitats on the Earth? 4) What kinds of cells need to exist in your body? Think of as many as you can. Part II: Video Questions 5) What benefits can come from habitat restoration? 6) If one plant costs $10 and needs 10 m2 of space, how much would it cost to restore five acres of habitat? (1 acre =4047 m2) 7) Explain the process of planting shoot cuttings. 8) What is the overall goal of the experiment? 9) Explain the processes of cell division and differentiation. 10) Why is it important to have a signal that causes cell division and differentiation? 11) Describe the treatments used in the experiment. 12) Which treatments were generally more effective and why? 13) Describe what happened at a cellular level when the stem cuttings received an effective treatment.

Cell Division
Part I: Pre-Video Questions
1. Provide a brief definition of the following terms to gain familiarity before watching the
a. Cell division is the process through which an individual cell segregates into two or more
daughter cells.
b. The cell cycle is the sequence of events occurring within a cell causing its segregation and
replication of its DNA to form two daughter cells.
c. Mitosis is a form of cell division involved with the production of two daughter cells which
are genetically identical to one another and their parent cell.
d. Cell differentiation is the process by which an immature and young cell develops into a
particular cell, obtaining its mature form and responsibility.
e. The hormone is an organic material released by plants and animals, which is responsible for
controlling the physiological processes and upholding homeostasis.
f. Gene expression is the process through which a genetic code is utilized in directing the
protein synthesis and producing the cell structures.
g. Shoot system is the essential part of a plant that develops above the ground, and it
incorporates organs such as flowers, buds, fruits, and leaves.
h. The root system is another essential plant part developing beneath the ground, and its roots
and improved stem structures like rhizomes and tubers.

i. Asexual reproduction is a form of reproduction that takes place when an organism formulates
more of itself exclusive of exchanging its genetic information with the next body via sex.
j. Habitat restoration is the process of seeking to renovate those areas that have been destroyed,
damaged or degraded.
2. Describe a time when you used a scientific approach to solve a problem.
