Keystone Biology Exam: Basic Biological Concepts - Chapter Objectives
The Keystone Biology Exam is an end-of-course test used in Pennsylvania to measure the academic achievement of students in a biology class. This chapter is relevant to Module 1: Cells and Cell Processes. The test is offered both online and in a paper-and-pencil format, and questions come in two types: multiple-choice and constructed-response. The test is not time-limited but is expected to take 144 minutes.
1. What are Cells? - Overview
All living organisms are made up of cells, but do you know what a cell is? In this lesson, you can learn about the three main structures that all cells contain and about the two major types of cells.
2. Eukaryotic and Prokaryotic Cells: Similarities and Differences
In this lesson, we discuss the similarities and differences between the eukaryotic cells of your body and prokaryotic cells such as bacteria. Eukaryotes organize different functions within specialized membrane-bound compartments called organelles. These structures do not exist in prokaryotes.
3. Structure & Function in Biological Organization: Benefits & Disadvantages
This lesson will discuss biological organization in terms of cells, tissues, organs, and organ systems. It will also discuss the benefits and disadvantages of multicellular versus single-celled organisms.
4. Living Systems Requirement for Free Energy and Matter
Free energy and matter are required by all living things in order to grow, reproduce, and maintain biological processes. Additionally, free energy and matter must also be recycled through the environment in order to remove dead material and allow for new growth.
5. The Environmental Requirements for Growth, Reproduction & Dynamic Homeostasis
Cells need to maintain internal environments that are different from their external environments in order to grow and reproduce. In this video lesson, you will understand some ways that cells can control their internal conditions to ensure proper biological functioning.
