  • light weight and huge
  • sticky and huge

The process of growth of seed in a plant is known as

  • pollination
  • reproduction
  • germination
  • fertilization

Some plants have seeds with hooks for

  • pollination
  • fertilization
  • dispersion

  • greasy
  • sticky
  • dry

If plants and animals do not reproduce, they would

  • sick
  • born
  • change
  • extinct

After the root has grown downwards, a small shoot grows upward, towards light. This shoot is known as

  • radicle
  • plumule
  • stem
  • cotyledon

The pollen grains of bird pollinated flowers are

  • lightweight and sticky
  • lightweight and slippery
  • huge and sticky
  • huge and slippery

The first part which comes out of a seed is

  • radicle
  • plumule
  • stem
  • cotyledon

When seed is sown into soil, the first thing which happens it

  • takes up water
  • takes up oxygen
  • bursts apart
  • splits into two parts

Insects pollinated flowers face

  • upwards
  • downwards
  • left
  • right

A part of plant which is found both in vegetable and fruit is known as

  • tuber
  • bud
  • runner
  • bulb

The ball formed in a plant is known as

  • zygote
  • embryo
  • endosperm
  • seed

The petals of the bird pollinated flowers have

  • less nectar but large amount of scent
  • large amount of nectar and scent
  • less nectar and scent
  • large amount of nectar but a little scent

Until the conditions are right for growth, the embryo remains

  • wet
  • dry
  • dormant
  • viable

For seeds the task of fruit is to

  • keep them fresh
  • protect them
  • disperse them only
  • protect and disperse them

The ovule turns into a

  • fruit
  • flower
  • ball of cells
  • ball of pollen grains

A part of plant that keeps on growing over the soil, making other small plants with penetrating roots in the soil and growing of shoots towards the light is known as

  • tuber
  • bud
  • runner
  • bulb

Stigma of wind pollinated flower is

  • sticky
  • feathery
  • plain
  • dry

After landing on stigma, the pollen grains

  • burst and form a tube
  • ripe and fall
  • burst and spread more small pollens
  • split and spread

Birds pollinated flowers have

  • tube shaped flower
  • bowl shaped flower
  • bulb shaped flower
  • plate shaped flower

The ball is surrounded by a special tissue known as

  • zygote
  • embryo
  • endosperm
  • seed

Asexual reproduction is also known as

  • anti-sexual reproduction
  • unisexual reproduction
  • vegetative reproduction
  • non vegetative reproduction

Flowers pollinated by means of insects, have

  • bright colored petals and attractive scent
  • dull colored petals and attractive scent
  • bright colored petals and bad smell
  • dull colored petals and bad smell

The miniature plants contain one or two seed leaves called

  • radicle
  • plumule
  • cotyledon
  • zygote

The transfer of pollen grains from anther to stigma of the same flower, or to the stigma of another flower on the same plant is known as

  • self reproduction
  • cross reproduction
  • self pollination
  • cross pollination

The male reproductive part of a flower contains two round shaped structures at their tip. These structures are known as

  • anthers
  • filaments
  • stamens
  • carpels

  • stamen

Fertilization occurs

  • after pollination
  • before pollination

  • without pollination

Mostly the color of sepal is
