……...is the site of transmittable influence that caused the bending of the entire……..

1.Coleorrhiza

2.Coleoptile

3.Auxin

4.Scutellum

Auxin was isolated by

1.F. W. Went

2.Charles Darwin

3.Francis Darwin

4.F. Skoog

Find the wrong match.

1.F. W. Went - Oat seedlings

2.Charles Darwin - Canary Grass

3.Francis Darwin - Canary Grass

4.E. Kurosawa- Orange

This picture suggests that

1. Tip of the coleorrhiza is the source of Auxin

2. Tip of coleoptile is the source of Auxin

3. Base of coleoptile is the source of Auxin

4. Base of coleorrhiza is the source of Auxin

Here arrows indicate

1.Source of Auxin

2.Direction of bending

3.Direction of light

4.Direction of cap removal
