Grade 10 - Reproduction Flashcards
What is Sexual Reproduction?
Like how does it happen and what are the characteristics blablabla
- Both result in at least one offspring
- It uses 2 parents to create an offspring
- Offspring features a combination of the parents genes
- It is typically found in much more complex organisms
- Takes a lot more time
What are the advantages of Asexual Reproduction?
- Rapid Population Growth
- No need for a mate
- Genetic Uniformity
What are the disadvantages of Asexual Reproduction?
- Accumulation of Mutations (Since offspring are basically clones of the parent, any mutations formed will never go away)
- Inability to adapt
- Overpopulation
What are the advantages of Sexual Reproduction?
- Genetic Diversity
- Increased Survival Rates
- Evolutionary Advantage
What are the disadvantages of Sexual Reproduction?
- Risk of Competition
- Lower Reproduction Rates
- Dependency on mates
What is the Cell Cycle?
The cell cycle consists of 2 main processes: Interphase & Mitosis
Describe Interphase
Interphase is by far the longest part of the cell cycle, and it essentially consists of the cell working normally, while growing and developing
Describe Mitosis
Mitosis is the process of the cell splitting and replicating. It results in 2 genetically identical daughter cells, each with a full set of chromosomes.
Also cancer is uncontrolled Mitosis lol
Describe Prophase
Before the splitting of the cell
Nucleus disappears
Chromosomes become individually identifiable
Centrioles move to the “poles” of the cell
Spindle begins to form
Describe Metaphase
Chromosomes line up in the middle of the cell
Spindle fibres attach to the centromeres
Describe Anaphase
Spindle Fibres pull apart sister chromatids (the halves of the chromosomes)
Chromosomes move towards opposite ends of the cell
Describe Meiosis
It produces gametes(sex cells) and it produces 4 genetically unique daughter cells, instead of 2 genetically identical ones. However, it is a Haploid cell, meaning it only has half a set of chromosomes. (The half set of chromosomes combines with the other half set of chromosomes in the sperm and egg cell)
Cytokinesis
This is the Division of the Cytoplasm
What are Flowers?
Flowers are organs for sexual reproduction in a flowering plant (angiosperm)
This technically means that flowers are plant dicks lol
What is an Angiosperm?
A flowering plant
e.g. roses, lilies, Broccoli, kale, Petunias, Aubergine, Tomato, Peppers, and sugarcane.
reminder that the flowers of these are dicks
