Plant Classification & Life Cycles
Unlike dandelions or fruit trees, non-flowering plants like mosses, ferns, and pine trees reproduce without ever producing these.
Flowers
These structures are often brightly colored to attract insects to the flower.
Petals
The two main methods of transferring pollen from one flower to another are insect pollination and this.
Wind Pollination
The primary job or purpose of a fruit in relation to its seeds is to protect them and carry out this process.
Seed Dispersal
This hard, protective outer covering splits open when a seed begins to germinate.
Seed Coat
Ferns, mosses, and pine trees belong to this broad category of plants.
Non-flowering plants
Found at the tip of the stamen, this male flower part is responsible for producing pollen grains.
Anther
Insect-pollinated flowers feature bright petals and sweet scents as adaptations to attract these.
pollinators (insects)
Dandelion seeds have parachute-like structures adapted to be dispersed by this method.
Wind
This term describes the process when a seed begins to grow and sprout into a young seedling.
Germination
In the life cycle of a flowering plant, this event occurs immediately after pollination occurs.
Seed formation
Located at the base of the carpel, this organ houses the plant's eggs.
Ovary
Flowers adapted for wind pollination typically lack bright petals and produce light, smooth pollen for this reason.
pollen can be easily carried by air currents
Heavy, fibrous fruits like coconuts move to new locations using this dispersal method.
floating on water
Inside a seed, this structure stores food and nutrients for the developing embryo until true leaves grow.
cotyledon (endosperm or food store)
This is the very first stage in the life cycle sequence of a flowering plant, occurring before the plant reaches maturity.
Seed germination
This sticky female part at the top of the carpel collects pollen grains during pollination.
Stigma
Pollination is vital to plants because it allows them to reproduce and form these.
Seeds
Seed dispersal is crucial for young plants because it prevents overcrowding and reduces this struggle for sunlight, water, and soil nutrients.
Competition
During the sequence of seed germination, this structure always emerges first from the seed coat.
First root (radicle)
Non-flowering plants like conifers make seeds inside cones rather than these structures produced by flowering plants.
Fruits
While the male reproductive organs of a flower are collectively called stamens, the female part is called this.
Carpel (Pistil)
Wind and animal pollination are considered more effective than self-pollination because they carry seeds and pollen further, promoting this benefit.
genetic diversity; wider seed distribution; cross-pollination
Pea pods and touch-me-not plants scatter their seeds away from the parent plant using this explosive method.
splitting or exploding
Warm temperatures and water are essential conditions for germination, but these two elements are NOT required at the start.
light and soil nutrients; [photosynthesis]
