Question

What are angiosperms? Plants that produce seeds. Plants that are vascular. Plants that produce flowers. All of these. Two of these. None of these. An aggregate fruit is formed from many carpels of many flowers. formed from tissues other than the ovary. formed from a single carpel. formed from many separate carpels of one flower. Identify the anther. Identify the sepal. Identify an ovary. Identify the stigma. The carpel consists of the anther and filament. the sepal and petal. the style and anther. the ovule and ovary. the stigma, style and ovary. the stigma and style. The pollination mechanism that requires the production of the greatest volume of pollen is pollination by bees. pollination by birds. pollination by bats. pollination by moths. pollination by wind. self-pollination. A bright color flower with sweet odor is usually pollinated by wind birds flies butterflies. Organisms that have been engineered to express a gene from another species are called transduced transformed transposed transgenic transferric The black dots that cover strawberries are actually fruits formed from the separate carpels of a single flower. The fleshy and tasty portion of a strawberry derives from the receptacle of a flower with a strawberry is a simple fruit with many seeds. both a multiple and accessory fruit. both a simple and aggregate fruit. both an aggregate and accessory fruit. What is does double fertilization mean? Two sperm fertilize, one for fruit and the other for seed production Two sperm fertilize, both to make the embryo. Two sperm fertilize, both for fruit production. All flower sperm have two nuclei. Two sperm fertilize, one for endosperm and the other to make the embryo. The four floral organs are sepals, petals, stamens and carpels. sepals, stamens, petals and anthers. sepals, styles, stamens and petal. sepals, stamens, anthers and ovaries.

Explanation / Answer

1) All of these

Angiosperms are vascular plants which bear seeds and this reproductive organs are flowers

2) formed by separate carpels of single flower

Aggregate fruit as formed by union of ovaries of single flower.Carpels contain ovaries and all the carpels combined to form aggregate fruit example strawberry.

3) option b is anther

The long filament contain anther at the tip it is very important in flowering plants as it produces male reproductive gamete called as pollen.

4) option D is sepal

Sepal is the green structures in flowering plants present below the flower sepal act as protective organ protecting flower during its bud stage.

5) option e is ovary

Ovary is female reproductive organ pollen reaches ovary through pollen tube and fertilization takes place.

6) option A is stigma

Ovary has long tube structure called as stigma.it act as pollen receptor and transfers pollen to ovary.

7) ovary style and stigma

Carpel consists of a combination of ovary, style and stigma seed development takes place inside of carpel.

8) pollination by wind

Plants pollinating by wind produces lots of pollens to increase chance of pollination.

9) butterflies

Butterflies are attracted by bright color flowers

10) transgenic

Transgenic are genetically engineered.

11) both aggregate and accessory fruit

Strawberry is called as aggregate fruit because is collection of ovaries and accessory fruit because entire tissue including ovary is part of fruit.

12) two sperms fertilize one for embryo and other for endosperm

Females gameto fuses with two sperms one produces endosperm and other producing embryo

13) a sepals,petals,carpels and stamen

Floral organs consists of petrals to attract organism for pollination, sepals give mechanical support to plant, carpels contains ovaries and stamen consists of male reproductive organs.
