2
Q

Production of offspring from vegetative organs

A

Asexual reproduction

3
Q

Production of offspring from union of gametes

A

Sexual reproduction

4
Q

Cost and benefit of asexual reproduction

A

Easy to propagate, not adaptable

5
Q

Cost and benefit of sexual production

A

Requires union, variation, adaptable

Complete flower

8
Q

Has one or two missing floral part

Incomplete flower

9
Q

Two positions of ovary

A

Superior, inferior (what’s the diff?)

10

Lacks one sex organ

12
Q

Flowr that has similar size and shape, has radial symmetry

A

Actinomorphic

13
Q

Flowr that has unequal size and shape, has bilateral symmetry

A

Zygomorphic

14
Q

Staminate and pistilate are on the same plant

A

Monoecious

15
Q

Have staminate OR pistilate

A

Dioecious

15
Q

Problem of plants

A

They are sessile/immobile

16
Q

It’s the megasporocyte (megaspore mother cell)

A

Ovary

17
Q

Egg development

A

Ovary- meiosis - megaspore (4, only one survives) - mitosis - egg

18
Q

Pollen development

A

Microsporocyte - pollen grain - male gametophyte - stigma - pollen tube growth - fertilization - zygote - seed growth - germination

19
Q

Types of placentation

A

Parietal, marginal, axial, locule

20
Q

Unfused carpel

A

Apocarpus

21
Q

Fused carpel

A

Syncarpus

22
Q

The transfer from stamen to stigma

A

Pollination

23
Q

2 types of vectors/agents of pollination

A

Abiotic (undirected = wastage) and biotic (directed)

24
Q

It is the stalk attached to the cell wall

A

Placental tissue

25
Q

How is an angiosperm created

A

Double fertilization (egg+sperm =zygote and polar nuclei+sperm)

26
Q

Triploid tissue that is the source of food

A

Endosperm

27
Q

Summary of fertilization

A

Pollen tube growth, double fertilization, zygote - embryo, central cell - endosperm, ovule - seed, ovary - fruit

28
Q

What is a seed and what does it contain?

A

Matured ovule; plant embryo, food supply, seed coat

29
Q

It contains a well- formed multicellular plant embryo

A

Embryo

30
Q

Other name for embryo

A

Germ

31
Q

This triploid can be the food source

A

Endosperm

32
Q

Outer layer of seed; forme from the integument

A

Seed coat

33
Q

Has a single fertilization; food source is the haploid megagametophyte

A

Gymnosperm seed

34
Q

Dicot vs monocot

A

Dicot
- 2 cotyledon
Monocot
- 1 cotyledon
