Asexual reproduction will produce what offpsring? | Vegetative structure (Roots,Stem,Leaves) |
Sexual reproduction will produce what? | Seeds, Flowers, Fruits |

Types of Flowers | 1 Perfect or Imperfect
2 Complete or Incomplete
3 Monoecious or Dioecious |
Has both male and female parts | perfect flower |
Missing either male or female parts | imperfect flower |
The flower has sepals, petals, pistil and stamen (complete four) | complete flower |
The flower has missing either sepals, petals, pistil and stamen (one of the four) | incomplete flower |
Imperfect flowers are always incomplete flowers
But Incomplete flowers may or may not be Imperfect flowers | .. |
If a plant has missing stamen or pistil, what is this type of plant? | imperfect flower |
If a plant has missing petal or sepal but stamen and pistil is still present, what is this type of plant? | perfect flower |
These are plants that contains male and female flowers on one plant | Monoecious |
Examples of monecious plants | corn, cucumbers, |
These plants have male and female flowers on separate plants | Dioecious |
Examples of dioecious plants | soybeans, asparagus, kiwi, rose, |
This is a cluster of flowers in the stem; arrangement of flowers in the stem, pedicle or peduncle | Inflorescence |
Types of Inflorescence | 1 Cyme
2 Spike
3 Raceme
4 Panicle
5 Corymb
6 Umbel
7 Spadix
8 Catkin
9 Head |
Describes the shape of the flower | Flower Symmetry |
Types of Flower Symmetry | 1 Asymmetric
2 Bilateral Symmetry
3 Biradial Symmetry
4 Radial Symmetry |
No mirror image of the flower | Asymmetric |
There is one plane portion of symmetry | Bilateral |
There is two plane portion of symmetry | Biradial |
More than one mirror image; all angles are mirror images | Radial |
What are the Ovary position of the plants? | 1 Hypogynous (Ovary Superior)
2 Perigynous (Ovary half-superior)
3 Epigynous (Ovary Inferior) |
Type of ovary position where hypanthium is missing and the petals and sepals are attached below the ovary | Hypogynous |
Tubular enlargement of the receptacle | Hypanthium |
Type of ovary position where the sepals and petals are attached in the mid portion of the ovary | Perigynous |
Types of ovary position where the sepals and petals are attached above the ovary | Epigynous |
It is a matured and ripened ovary | Fruit |
What can you find inside fruits | Seeds |
Transfer of pollen grains from male parts(Anther) to the female part (stigma) | Pollination |
Two types of pollination | 1 Self pollination
2 Cross pollination |
Pollination that occurs within the same flower or separate flowers within the same plant | Self pollination |
Example of flower that do self pollination | Gumamela |
When pollen grains are transferred to a flower on another plant; involves two different plants | Cross pollination |
Examples of flowers that do Cross pollination | Corn, melon, cucumber |
Cross pollinators are what flowers? | Imperfect flowers |
Pollination and Fertilization Process (STEP-BY-STEP) | Pollination ->
Fertilization ->
Embryo development ->
Mature seed ->
Fruit |
Fertilization Process (STEP-BY-STEP) | 1 Pollen grain will travel down the pollen tube inside the style; pollen grain contains two sperms
2 The sperm will travel down to the ovules through microphyll entry
3 Once inside the ovule, it will unite with female gemetes
4 It will produce two products which is a diploid zygote and triploid endosperms
End products: Diploid Zygote and Triploid Endosperms |
What is the function of Triploid Endosperms? | A food source for the growing embryo |
Diploid Zygote contains what? | Stored nutrient in a compact seed which will eventually develop to a mature seed which contains Embryonic plant and endosperms and cotyledons.
Inside the Ebryonic plant: Radicle, Plumule, Hypocotyl |
The Embryonic plant contains what? | 1 Radicle
2 Plumule
3 Hypocotyl |
Develops into root | Radicle |
Develops into food | Plumule |
Extra food and storage for the seed | Cotyledon |
A process by which a plant grows from a seed | Seed Germination |
Types of Fruits | 1 Simple Fruits
2 Aggregate Frutis
3 Multiple Fruits
4 Accessory Fruits |
They only have one seed | Monocot |
They have two seeds | Dicot |
Fruits provide protection and dispersal for the enclosed seeds | .. |
This fruit usually develops from one or several united carpels or ovary | Simple Fruit
Ex. Berry, drupe, follicle, legume, capsule, caryopsis, achene, nut |
A fleshy fruit with soft tissues that contains few or many seeds
tomato, grapes, banana, cranberry, blueberry | Berry |
Simple fleshy, fibrous fruits that contains a hard stone which contains the seed
avocado, olives, peaches, almonds | Drupe |
Dry fruits at maturity, but does not split open at maturity | Indehiscent Fruits |
Indehiscent Fruits | 1 Caryopsis (grain of rice, seed coat is fused in the fruit wall)
2 Achene (seed coat is not fused to the fruit wall; sunfower fruit)
3 Nut (Stony wall; chehstnuts, acorn)
peanuts and almonds are not nuts |
Simple fruits that dry and splits open along their suture to release their seed | Dry dehiscent Fruits |
Dry dehiscent Fruits | 1 Follicle (splits open along one suture only)
2 Legume (splits open at two suture-top or bottom-)
3 Capsule (split open along multiple sutures) |
Develops from a single flower with several separate carpels that fuse or grow together | Aggregate Fruits |
Forms from the carpels of the many flowers which usually grows close to one another on a common floral stock | Multiple Fruits |
The fleshy part is composed primarily of tissue other than the ovary | Accessory Fruits |
