Acid or Base
If a liquid doesn't change the cabbage color at all, we call it this.
Neutral
What color does anthocyanin change when exposed to baking powder?
Blue
This vitamin is also known as ascorbic acid and would turn red cabbage indicator pink in high concentration because it is acidic.
Vitamin C
This green pigment absorbs light energy for photosynthesis.
Chlorophyll
The basic unit of life.
Cell
There is Solution 1 which has a pH of 3.0. There is solution 2 which has a pH of 5.5. Which is more acidic?
Solution 1
When the environment becomes acidic, anthocyanins often turn ______.
Red, Pink
Unlike fat-soluble vitamins, these are generally not stored extensively and must be consumed regularly.
Water-soluble vitamins
Some plants can digest insects to obtain nutrients in nutrient-poor environments.
Carnivorous plants
The movement of molecules from an area of high concentration to low concentration without energy input.
Diffusion
This is the specific "Ion" that acids release when dissolved in water, which turns the cabbage juice red.
H+ or H3O+
Anthocyanins are water-soluble. Because of this, when you boil red cabbage, the water turns purple. This is different from the green pigment in leaves, called this, which doesn't dissolve in water easily.
Chlorophyll
How many essential vitamins do you need for healthy body function?
13 (Thirteen)
This plant tissue transports water and minerals upward from the roots and to the leaves.
Xylem (primary vascular tissue)
The process by which organisms maintain a stable internal environment.
Homeostasis
While acids have lots of Hydrogen ions, Bases have a high concentration of this ion.
Hydroxide OH-
Match the food to its likely anthocyanin color: Blueberry → A)Deep Purple
Red cabbage → B) Blue
Black rice → C) Reddish Purple
Purple sweet potato → D) Dark Violet
Blueberry B
Red Cabbage C
Black Rice D
Purple Sweet Potatio A
This vitamin deficiency can cause night blindness, and because it is fat-soluble, it would not significantly affect the color of a water-based anthocyanin indicator solution.
Vitamin A
Plants can reproduce without seeds using runners or cuttings.
Asexual (vegetative) reproduction
What do you call when lions and hyenas compete for the same prey? (remember this is 400)
Interspecific Competition
What is the formula for pH when a concentration of acid is given
-log[H3O+]
The word "Anthocyanin" comes from two Greek words: anthos, meaning flower, and kyanos, which means this specific color. (Think about the colors of the vegetables that has anthocyanin)
Blue
Match the vitamin to its main function:
Vitamin A →
Vitamin C →
Vitamin D →
Vitamin K →
A) Blood clotting B) Bone health C) Vision D) Immune system support
VA-> Vision VC-> Immune system support VD-> Bone Health VK-> Blood Clotting
When anthocyanins change color based on the pH of their environment, it is primarily called what?
Halochromism
If an enzyme’s shape is altered due to extreme pH, it is said to be this.
Denatured
