   • Biology

2. The process by which plants convert light energy into chemical energy is called ___________.

   • Photosynthesis

3. The basic unit of structure and function in living things is the ___________.

   • Cell

4. The process by which a cell obtains energy from food is called ___________.

   • Metabolism

Short Answer Questions

1. Describe the process of photosynthesis.

Photosynthesis is the process by which green plants use light energy from the sun to convert carbon dioxide and water into glucose (sugar) and oxygen. This process involves the use of chlorophyll, which absorbs the light energy and uses it to convert the carbon dioxide and water into the glucose and oxygen. The glucose is then used by the plant for energy, and the oxygen is released into the atmosphere.

Biology Practice Sheet

Introduction

Biology is the scientific study of life and living organisms. It is a vast subject, and this practice sheet will help you gain a better understanding of the basics.

Section 1: Cells

Cells are the fundamental unit of life. All living organisms are made up of cells, and they are the basic building blocks of life.

1. What are the two main types of cells? A. Prokaryotic and Eukaryotic

2. What is the difference between prokaryotic and eukaryotic cells? A. Prokaryotic cells are simpler and lack a nucleus, while eukaryotic cells are more complex and have a nucleus.

3. What are the three main components of a cell? A. The cell membrane, cytoplasm, and nucleus.

4. What is the function of the cell membrane? A. The cell membrane is a selectively permeable barrier that allows certain substances to enter and exit the cell.

Section 2: DNA

DNA is the genetic material that is found in all living organisms. It is responsible for the transmission of genetic information from one generation to the next.

1. What is the structure of DNA? A. DNA is a double-stranded molecule that consists of two strands of nucleotides linked together by hydrogen bonds.

2. What is the purpose of DNA? A. DNA contains the genetic information that is necessary for the development and functioning of living organisms.

3. What are the four nitrogenous bases found in DNA? A. Adenine, Thymine, Guanine, and Cytosine.

4. What is the purpose of DNA replication? A. DNA replication is the process by which a cell creates an exact copy of its DNA in order to pass on genetic information to its daughter cells.

Section 3: Genetics

Genetics is the study of heredity and the variation of inherited traits from one generation to the next.

1. What is the difference between a gene and an allele? A. A gene is the basic unit of heredity, while an allele is a variant form of a gene.

2. What is the difference between genotype and phenotype? A. Genotype refers to the genetic makeup of an organism, while phenotype refers to the physical characteristics of an organism.

3. What is the process of meiosis? A. Meiosis is the process by which a single cell divides into four daughter cells, each with half the number of chromosomes as the parent cell.

4. What is the purpose of genetic engineering? A. Genetic engineering is the process of introducing specific changes to an organism's genetic makeup in order to produce desired traits.
