Botany: Week 7 - Pollination and Eucalypt Characteristics

A set of vocabulary flashcards focusing on key terms and definitions related to pollination, reproduction in plants, and specific characteristics of eucalypts.

Pollination

The transfer of pollen from the anther to the stigma of the same or another flower.

Autogamy

Self-pollination of a flower.

Anemophily

Pollination by wind.

Hydrophily

Pollination that occurs under water.

Mellitophily

Pollination by bees.

Ornithophily

Pollination by birds.

Dioecy

Sexual reproductive strategy where male and female flowers are on separate individual plants.

Monoecy

Reproductive strategy where male and female flowers are on the same plant.

Protandry

A condition where the pollen is mature before the stigma is receptive.

Protogyny

A condition where the stigma is receptive before pollen is mature.

Self-incompatibility

A mechanism where self-pollination does not result in fertilization.

Double fertilisation

A process in flowering plants where one sperm fertilizes the egg cell and another sperm combines with two polar nuclei to form the endosperm.

Eucalyptus

A genus of trees and shrubs, predominantly found in Australia, known for their oil-rich leaves.

Corymbia

A genus of flowering plants previously classified under Eucalyptus.

Myrtaceae

The family that includes eucalypts, characterised by aromatic leaves and essential oils.

Calyptra

A cap-like structure that covers the flower buds in the genera Eucalyptus and Corymbia.

Sporophytic self-incompatibility

Self-incompatibility that occurs when the pollen is rejected on the stigma based on the sporophyte genotype.

Gametophytic self-incompatibility

Self-incompatibility that occurs when the pollen is rejected in the style based on the male gametophyte genotype.

Eucalypt bark types

Classification of bark into smooth barks and rough barks based on how they shed and renew.

Selective seed abortion

The process by which some seeds are aborted to enhance the chances of survival of the rest, often related to pollination failure.

Vascular tissue

Specialized tissue responsible for the transport of water, nutrients, and sugars in plants.
