Reproduction in plants

?
Characteristic of sexual reproduction (think of asexual)
Gametes produced. Fertilisation takes place. Genetic variation in offspring
1 of 16
Characteristic of Asexual reproduction (think of sexual)
No gametes, no fertilisation, no genetic variation
2 of 16
What is asexual reproduction
Involves parts of a plant to grow and break away from the parent plant before developing into a new plant
3 of 16
Examples of asexual reproduction in plants
Runners, Tubers (potatos), Bulbs

Steps of plant cutting (1)
Use a clean scalpel to cut off the shoot at a length about 3-5 inches. Remove lower leaves and scales at leaf stalk base leave at least 2. Dip the base into root hormone powder

Steps of plant cutting (2)
Add compost or peat based compost to plant pot. Make a small hole in the compost. Insert cuttings with care. Water the cutting. Place in warm spot
6 of 16
Part of a plant dealing with reproduction
Petal, pollen, stamen(anther, filament), stigma, style, ovary, ovule, stem, receptacle, sepal
7 of 16
What is self pollination
Transfer of pollen grains from the anther to the stigma of the same flower
8 of 16
What is cross pollination
Transfer of pollen from an anther of one flower to the stigma of another flower
9 of 16
Features of insect-pollinated flowers
Stamens are enclosed. Enclosed stigma and sticky. Large coloured petals. Nectaries and large pollen grains
10 of 16
Features of wind-pollinated flowers
Exposed stamens. Exposed and feathery stigma. Small not coloured petals. No nectaries. Small Pollen Grains
11 of 16
What is fertilisation
the action or process of fertilising an egg
12 of 16
What is fertilisation in plants
Nucleus if the pollen grain must fuse with the nucleus of the ovum, which is inside the ovule in the ovary
13 of 16
What is germination
the process by which an organism grows from a seed. Essentialy a plant embryo. Consists of a root, shoot and one or two seed leaves called cotyledons
14 of 16
What is monocotyledonous and dicotyledonous
Plants that have only one cotyledones. Two for the other
15 of 16
What are the following conditions for germination
Warm temperatures. Water. Oxygen
