Anyone who needs help learning or mastering middle school life science material will benefit from taking this course. There is no faster or easier way to learn middle school life science. Among those who would benefit are:
- Students who have fallen behind in understanding chemical control of growth or dealing with the life cycle of plants
- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning science (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about how plants grow and reproduce
- Students who struggle to understand their teachers
- Students who attend schools without extra science learning resources
How it works:
- Find videos in our course that cover what you need to learn or review.

Students will review:
This chapter helps students review the concepts in a plant growth and reproduction unit of a standard middle school life science course. Topics covered include:
- The gametophyte and sporophyte
- Seasonal growth cycles
- Plant hormones
1. Alternation of Generations: The Gametophyte and Sporophyte
Even though many plants seem simple, they often have very complex life cycles. We will look at how plants alternate between different life stages as well as the terms used to describe these unique points in their life cycle.
2. A Moss Life Cycle: Dominant Gametophyte
Mosses are unique because they spend most of their lives with only one set of genetic material rather than the normal two sets. We will look at this cycle and how the alternation of generations takes place in these non-vascular plants.
3. A Fern Life Cycle: Plant Reproduction Without Flowers or Seeds
Ferns are able to reproduce without using seeds. We will look at how ferns reproduce as well as the pattern of alternating between diploid and haploid life stages.
4. A Gymnosperm Life Cycle: Reproduction of Plants with 'Naked Seeds'
Some plants, such as pine trees, are able to reproduce with unprotected seeds. We will look at the major structures involved in this form of alternation of generations in gymnosperms.
5. An Angiosperm Life Cycle: Flowering Plant Reproduction
When you think of how plants reproduce, you probably think of flowers. We will look at how flowering plants use specialized reproductive structures to complete an alternation of generations life cycle.
6. Tropisms: Phototropic, Geotropic and Thigmotropic Plant Growth
Animals aren't the only things that can respond to the environment. While plants may seem inanimate at times, they, too, can respond to the environment in order to better survive.
7. Photoperiodicity: Short-day, Long-day and Day-Neutral Plants
Ever wonder why some plants will bloom in the spring but others in the summer? The length of daylight can influence when a flower will bloom. We will look at how the amount of sunlight regulates when plants produce flowers.
8. Seasonal Growth Cycles: Perennial, Annual and Biennial Plants
We continue to grow and change throughout our entire lives, living through many seasons and years. Plants have different patterns of growth and development regarding seasons, which we will look at in this lesson.
9. Plant Hormones: Chemical Control of Growth and Reproduction
We most often think of hormones as things that control our actions and development. However, even plants have these chemicals to help regulate growth and reproduction.
10. Incomplete Flowers: Examples & Structure
Many people assume that all flowers have the same parts. In this lesson, we will investigate incomplete flowers. We will see what makes a flower incomplete, and look at common examples of them.
11. What Are Annual Plants? - Definition & Examples
All plants have individual needs and complete their life cycle in unique ways over a period of time. In this lesson, we will learn about a group of plants known as annuals.
12. Venus Flytrap: Life Cycle, Dormancy & Reproduction
Want to learn more about a plant that is a little like an animal? The Venus flytrap is a fascinating creature, and this lesson will explore its life cycle (including dormancy) as well as how it reproduces.
13. Ascomycota: Life Cycle & Classification
We need fungi for everything from producing food to creating antibiotics to cleaning up decayed organisms. We are going to discuss the life cycle and classification of Ascomycota.
14. Fragmentation & Regeneration Reproduction in Plants & Animals
All plants and animals reproduce in different ways. In this lesson, we discuss a type of reproduction called fragmentation and the process of regeneration that occurs with it.
