A large, green leaf with a network of veins clearly visible. Sunlight is shining down on the leaf, represented by yellow - orange rays. Carbon dioxide molecules, shown as small, gray - colored circles with two oxygen atoms attached, are entering the leaf through tiny pores called stomata. Water is being drawn up from the roots, depicted as blue - colored lines traveling through the stem to the leaf. Oxygen, represented by pairs of small, red circles, is being released into the air from the leaf, black and white coloring page.

A desert plant with thick, fleshy leaves. The plant is adapted to store water. Sunlight, in a bright yellow - orange color, beats down on the plant. The roots of the plant are long, reaching deep into the dry soil to absorb water, shown as blue lines. Carbon dioxide, in gray, is present in the dry desert air, and the plant is releasing red - colored oxygen, black and white coloring page.

A plant on a mountainside. The air is thin, but the sun shines brightly, with yellow - orange rays. The plant has adapted to the high - altitude environment, with its roots firmly gripping the rocky soil. Blue lines show water being absorbed from the mountain soil. Gray carbon dioxide in the thin air reaches the plant, and red oxygen is being given off, black and white coloring page.

A cactus in a desert oasis. The cactus has thick, spiny stems that act as leaves. Sunlight, in a harsh yellow - orange, shines on the cactus. Its roots spread out in the oasis soil to absorb water, shown as blue lines. Gray carbon dioxide in the desert air reaches the cactus, and red oxygen is being released, coloring page.

A group of plants in a garden. Some are tall, like sunflowers, and some are low - lying, like marigolds. The sun is high in the sky, casting yellow - white sunlight over the entire garden. Each plant has roots in the soil, with blue water - uptake lines. Gray carbon dioxide molecules are in the air around the plants, and red oxygen molecules are being released from the leaves, creating a sort of red - hued mist above the garden, black and white coloring page.

A greenhouse filled with various plants. The glass of the greenhouse allows yellow - white sunlight to enter. Each plant has its roots in pots filled with soil, and blue lines show water movement. Gray carbon dioxide is present in the enclosed greenhouse air, and red oxygen is being released, creating a fresh - smelling environment inside the greenhouse, black and white coloring page.

A group of ferns in a shaded forest area. Although the sunlight is filtered through the tree canopy, it still reaches the ferns as a pale yellow - green light. The ferns have fronds with many small leaflets. Their roots are in the moist forest floor, taking up water (blue lines). Carbon dioxide, in gray, is present in the damp forest air, and the ferns are releasing red - colored oxygen, black and white coloring page.

A plant in a backyard vegetable garden. The plant is a tomato plant, with green leaves and small, green tomatoes. The sun, in a warm yellow - orange, shines on the garden. The plant's roots are in the fertile soil, taking up water (blue lines). Gray carbon dioxide from the surrounding air is used for photosynthesis, and red oxygen is being released, black and white coloring page.

A tree in a forest. Its large, green leaves are spread out. The forest floor is covered with fallen leaves and soil, where the tree's roots are deeply embedded. Blue lines show water traveling from the roots through the trunk and branches to the leaves. Yellow - orange sunlight filters through the canopy. Gray carbon dioxide molecules are present in the forest air, and red oxygen molecules are being given off by the tree's leaves, black and white coloring page.

A vine - like plant climbing up a trellis. Its green leaves are exposed to the sun. The plant's roots are in the soil at the base of the trellis, with blue water - uptake lines. Carbon dioxide from the surrounding air is approaching the plant, and red oxygen is being emitted from the leaves, black and white coloring page.

A plant in a hydroponic system. Instead of soil, the plant's roots are suspended in a nutrient - rich water solution. The system is under artificial lights, shown as white - yellow bulbs. Blue lines represent the water and nutrient flow to the plant. Gray carbon dioxide is pumped into the area around the plant, and red oxygen is being produced by the plant's leaves, black and white coloring page.

A microscopic view of a leaf cell. Inside the cell, there are green - colored chloroplasts, where photosynthesis takes place. Yellow - orange sunlight is shining on the cell. Carbon dioxide molecules enter the cell from the left side, and water molecules, shown as small blue - colored structures, are also present. Oxygen molecules, in red, are being produced inside the chloroplasts and are about to be released from the cell, black and white coloring page.

A small, young plant just sprouting from a seed. The seedling has two small, green leaves. Sunlight, in a soft yellow - orange, shines on the plant. The roots are starting to grow into the soil, taking up water shown as blue lines. Gray carbon dioxide molecules are in the air around the seedling, and the plant is beginning to release red - colored oxygen, black and white coloring page.

A plant in a space - based greenhouse. The greenhouse is made of special materials to protect from radiation. Artificial sunlight, in a bright white - yellow color, is provided. The plant's roots are in a special growing medium. Blue lines show the supply of water and nutrients. Gray carbon dioxide is recycled within the space - based system, and red oxygen is being produced, black and white coloring page.
