In this lesson our instructor talks about subcellular structure. First, she talks about prokaryotic cells. Second, she talks about eukaryotic cells structure. Then she talks about the cytoskeleton. Finally she talks about plant cell structure. Four complete example videos round up this lesson.
have cell walls containing peptidogylcan. Some bacteria are covered
by a capsule that helps them to evade the immune system.
genetic material in bacteria found in the nucleoid region. Some
bacteria also have small rings of DNA called plasmids, which contain
are projections from the bacterial surface. Sex pili transfer DNA
from one cell to another.
provide a means of motility in some prokaryotes.
cells contain membrane bound organelles including rough and smooth
endoplasmic reticulum, Golgi apparatus, mitochondria, lysosomes,
peroxisomes and ribosomes.
DNA is organized as chromosomes bound by histone proteins and is
located within a membrane bound nucleus. The nucleolus is the site
of ribosomal RNA synthesis.
cytoskeleton is a network of filaments composed of microtubules,
microfilaments and intermediate filaments.
cells do not have cell walls. The primary cell walls in plants
contain cellulose. Plants may also have a secondary cell wall
composed of both cellulose and lignin.
cells have a large central vacuole and organelles called plastids,
including chloroplasts, the site of photosynthesis.
Lecture Slides are screen-captured images of important points in the lecture. Students can download and print out these lecture slide images to do practice problems as well as take notes while watching the lecture.
The book and CD package include three full length practice exams that are presented with all questions answered and explained. The author also presents detailed reviews of all test topics and includes multiple-choice and free-response questions with answers at the end of each topic's chapter.
This book has a great topic-by topic breakdown of the 14 must-know principles with sample questions and answers for each of the subjects. Laboratory Review includes a focused review of all 12 AP laboratory exercises. Included in this is 2 full length practice tests that stimulate the actual test along with answers and complete explanations.
This book includes a comprehensive biology test topic review, covering everything from photosynthesis to genetics to evolution. Cracking the AP Biology also includes testing strategies for the grid-in and essay section, great guidance on writing a high-scoring essay, and two full length practice exams with detailed explanations.
