So where do these fit in?

Plant ModificationsEvolution has allowed for the modification from

the basic plant structures you have already learned.

Example 1: Make a prediction

Record in your notebook what modified part of a plant these might be.

Bulbs (like onions and garlic), thorns, and tendrils are all examples of modified shoots (stems and leaves).

Bulbs: These shoots are an adaptation for interrupted life....for existence in environments with a dormant season due to annual rainfall variations or to life in the temperate climates.

Thorns: Needed for protection against predation

Tendrils: Tendrils of grape are modified flowering shoots.

Shoots

StemsThese are actually all examples of modified

stems (not leaves).

Succulent/photosynthetic Stems: In extremely dry environments, often the leaf becomes reduced and non-photosynthetic, and the stem becomes the primary photosynthetic organ of the plant. A barrel shape provides a low surface to volume ratio which reduces water loss.

LeavesSpines for Defense: The non-photosynthetic

leaves of cacti have become modified for defense.

Pitcher Plants: These are adapted for life in marshy/boggy nitrogen poor soil. The leaves are passive but lethal to insects.

Venus Fly Traps and Sundew: These are in the same family. They are adapted for life in wet nitrogen poor soils and both entrap insects.

RootsAerial roots are roots above the ground. They

are almost always adventitious. They are found in diverse plant species, including epiphytes such as orchids, tropical coastal swamp trees such as mangroves, the resourceful banyan trees, the warm-temperate rainforest.

Video QuestionsAnswer these questions in your notebook

please!

1. What two strategies has the orchid adapted to attract the wasps?

2. What is the benefit of these adaptations to the orchid

3. Come up with a hypothesis for how the wasp might evolve to avoid how the orchid essentially “tricks” the wasp.
