Plant Reproduction

Sexual Reproduction:

  • Sepal → protection and stability

  • Petals → Protection and attractiveness (Attracts pollenators)

  • Stamen → Overall part of the male reproductive system

    → Filament: Keeps anther in the air

    → Anther: Produces pollen → Includes gamlets → Pollen has 2 male sex cells.

  • Carpal → Overall part of the female reproductive system

    → Stigma: Sticky surface that captures pollen beggins fertilisation process

    → Style:

    → Ovary → Ovules:

Pollenation is the production and transport of pollen

Fertilisation is when the pollen attaches to the stigma

  1. Tube Cell: Creates a pathway down the female plan reproductive system for Generative Cell

  2. Generative Cell: Follows pathway to ovary and splits into two and one cells is for fertilisation and creates a seed and the other cell is creating the endosperm which is the fruit/nutrition

Dispersal of fruit + seeds creates new plants = Sexual Reproduction

Main pollenators:

  1. Wind

  2. Water

  3. Bees

  4. Insects

  5. Birds

Sexual Reproduction

  • 2 Parents

  • Slow process

  • Variation in offspring

Asexual reproduction

  • 1 Parent

  • Fast process

  • Identical offsrping

1st process - Through Leaves

  1. Small buds form on edge of leaf

  2. Get bigger - grows roots and shoots

  3. Then fall off and grow new plant

2nd process - Through Stem

Runners:

  1. Stem grow off another stem and above ground

  2. Stem will grow, roots and shoots develope\

  3. Break off and new plant forms

Tubers:

  1. Branches off roots

  2. Swollen stems underground

  3. Breaks off parent plant

3rd Process - Through roots

  • Roots grown underground

  • Buds on roots grow upward into shoot

  • Shoots become plants

All three processes

  • Something new grows

  • Roots and shoots develope

  • A new plant grows
